Production of renewable biofuels and chemicals by processing bio-feedstock in conventional petroleum refineries

Vu, Xuan Hoan, Nguyen, Sura, Dang, Thanh Tung, Armbruster, Udo, Martin, Andreas 09 December 2015 (has links)
The influence of catalyst characteristics, i.e., acidity and porosity on the product distribution in the cracking of triglyceride-rich biomass under fluid catalytic cracking (FCC) conditions is reported. It has found that the degradation degree of triglyceride molecules is strongly dependent on the catalysts’ acidity. The higher density of acid sites enhances the conversion of triglycerides to lighter products such as gaseous products and gasoline-range hydrocarbons. The formation of gasolinerange aromatics and light olefins (propene and ethene) is favored in the medium pore channel of H-ZSM-5. On the other hand, heavier olefins such as gasoline-range and C4 olefins are formed preferentially in the large pore structure of zeolite Y based FCC catalyst (Midas-BSR). With both catalysts, triglyceride molecules are mainly converted to a mixture of hydrocarbons, which can be used as liquid fuels and platform chemicals. Hence, the utilization of the existing FCC units in conventional petroleum refineries for processing of triglyceride based feedstock, in particular waste cooking oil may open the way for production of renewable liquid fuels and chemicals in the near future. / Bài báo trình bày kết quả nghiên cứu khả năng tích hợp sản xuất nhiên liệu sinh học và hóa phẩm từ nguồn nguyên liệu tái tạo sinh khối giầu triglyceride bằng công nghệ cracking xúc tác tấng sôi (FCC) trong nhà máy lọc dầu. Kết quả nghiên cứu cho thấy xúc tác có ảnh hưởng mạnh đến hiệu quả chuyển hóa triglyceride thành hydrocarbon. Tính acid của xúc tác càng mạnh thì độ chuyển hóa càng cao và thu được nhiều sản phẩm nhẹ hơn như xăng và các olefin nhẹ. Xúc tác vi mao quản trung bình như H-ZSM-5 có độ chọn lọc cao với hợp chất vòng thơm thuộc phân đoạn xăng và olefin nhẹ như propylen và ethylen. Với kích thước vi mao quản lớn, xúc tác công nghiệp FCC dựa trên zeolite Y ưu tiên hình thành C4 olefins và các olefin trong phân đoạn xăng. Ở điều kiện phản ứng của quá trình FCC, triglyceride chuyển hóa hiệu quả thành hydrocarbon mà có thể sử dụng làm xăng sinh học cho động cơ và olefin nhẹ làm nguyên liệu cho tổng hợp hóa dầu.

[en] CIRCULAR ECONOMY IN BRASIL: BARRIERS AND DRIVERS TO THE RECOVERY AND RECYCLING BUSINESS OF WASTE COOKING OIL / [pt] ECONOMIA CIRCULAR NO BRASIL: BARREIRAS E OPORTUNIDADES PARA O NEGÓCIO DE RECUPERAÇÃO E RECICLAGEM DO ÓLEO DE COZINHA RESIDUAL

MELISSA CASACCHI ANTUNES 04 May 2020 (has links)
[pt] A Economia Circular (EC) é apontada como um mecanismo para o desenvolvimento sustentável, e um caminho para mitigar a problemática da geração de resíduos. Na EC o resíduo é recurso em uma nova cadeia produtiva; na prática, isto ocorre por meio do negócio de Recuperação e Reciclagem (RR). No Brasil, o debate sobre EC ainda é exíguo e são poucos os estudos acadêmicos publicados. Com objetivo de identificar as barreiras e as oportunidades para implantar um negócio de RR, à luz da EC, foi realizado um estudo de caso na cadeia de reaproveitamento do óleo de cozinha residual (OCR). Os métodos utilizados na pesquisa qualitativa foram: revisão bibliográfica, análise documental, entrevistas e observação participativa. Observou-se que a RR do OCR ocorre por meio de uma rede circular, composta por diversos agentes, com interesses e estratégias individuais que não incluem o ciclo de vida do produto. Os agentes intermediários, atuantes na logística reversa, são motivados por questões socioeconômicas. As barreiras se manifestam em seis segmentos: sociocultural, organizacional, tecnológico, de mercado, econômico e regulatório; são coincidentes com o quadro teórico, contudo estão associadas às condições socioeconômicas locais e à maturidade da indústria para EC. As oportunidades na EC convergem para o desenvolvimento sustentável. Esta pesquisa sugere que a responsabilidade estendida do produtor e o incentivo à aquisição de recurso secundário são estratégias primordiais para fechar o ciclo de vida do produto; contribui também com informações para tomada de decisão no setor de RR. / [en] Circular Economy (CE) has been pointed as a mechanism to reach sustainable development, also an answer to solid waste challenges. Under CE concept waste is resource in a new supply chain. Recovery and Recycling (RR) is one of the CE business model to turn waste into value. Therefore, CE represents a strategic path for the field of Urban Solid Waste Management. It is expected to bring innovation to this sector and foster large change in waste treatment practices in order to closing the loop. In Brazil, the debate about CE is still in the early stages and there are limited academic studies launched. In order to identify barriers and drivers to implement the CE business model of Recovery and Recycling in Brazil, a singular case study was conducted in the waste cooking oil (WCO) recovery supply chain. Moreover, considering the differences between common recycling practices in the local context and CE RR business model, it is needed to set the studied WCO recycling supply chain into the framework of the CE recovery and recycling business model.

Estudio de la optimización de estufas de cocción tradicionales empleadas en países en desarrollo utilizando biomasa leña gasificada (aplicado a la R.D.Congo)

Mulumba Ilunga, Óscar 02 March 2021 (has links)
[ES] Resumen Casi la mitad de la población mundial no tiene acceso a energías como la electricidad o el gas y tienen que utilizar forzosamente biomasa para cocinar, principalmente leña y carbón. Lo que en países desarrollados parece un lujo, en otros muchos es una obligación, ya que no hay otra alternativa. Con un pequeño ahorro en el combustible que utilizan estas estufas de los países sin acceso a otro tipo de energía, el resultado global es extraordinario. En el caso de la República Democrática del Congo más del 80% de la población realiza sus actividades culinarias utilizando biomasa sólida (leña, carbón vegetal, etc.) Para cocinar en las zonas rurales y los extrarradios de las grandes ciudades se utiliza la tradicional estufa de tres piedras TCS-3P y en las zonas urbanas la tradicional estufa de carbón vegetal TCS-C. La principal desventaja de esta práctica es una combustión de baja eficiencia energética, con la consecuencia directa de un consumo excesivo de materias primas como carbón y leña y la correspondiente deforestación. Estos equipos de cocina tradicionales emiten muchos contaminantes perjudiciales para la salud (CO y PM), así como y emisiones que contribuyen al calentamiento global y al cambio climático (CO2 y BC). En este trabajo proponemos modelos para mejorar la eficiencia energética utilizando el modelo tradicional como punto de partida, tal como lo utiliza la comunidad local. Para las poblaciones que viven en condiciones muy críticas y precarias, se han propuesto "insertos de cerámica" que pueden fabricarse y añadirse a las estufas que utilizan en la actualidad. Estos insertos pueden actuar sobre el rendimiento con mejoras del 15%. Se ha propuesto y analizado una segunda mejora basada en la combustión natural de la estufa de carbón ICS-C. El modelo más prometedor es la estufa que utiliza el principio de micro gasificación de la biomasa. Se han diseñado dos modelos de esta estufa, el modelo ICS-G1 con un solo reactor de combustión y el modelo ICS-G2 con dos reactores de combustión, y se han realizado análisis de sostenibilidad con aplicación directa a las comunidades locales. El modelo de micro gasificación propuesto funciona con un suministro de aire forzado con una gran flexibilidad de variación de la potencia de fuego según el tipo de comida a cocinar. El sistema de suministro de aire es provisto por un pequeño motor alimentado por energía solar con autonomía proporcionada por una pequeña batería de litio recargable. Los modelos de gasificación muestran importantes ventajas en comparación con el sistema tradicional, mejor eficiencia energética, al necesitar menos de la mitad de leña que con la tradicional, reducciones drásticas de las emisiones contaminantes y atmosféricas, con un ahorro de emisiones de CO2 en la ciudad de Kinshasa estimadas en 3405 kton/año y una reducción de casi la mitad del tiempo dedicado a la preparación de alimentos. Estas estufas pueden utilizar todo tipo de combustibles sólidos, además del carbón, se realizaron ensayos con combustibles alternativos que provienen de residuos agrícolas (BSW3) de esta forma se limita la presión ejercida sobre los bosques debido al uso de leña para cocinar. Los métodos de prueba utilizados son la prueba de ebullición del agua y la prueba de cocción controlada, con esta última se realiza una preparación de alimentos en un ambiente controlado. Los resultados de estas mejoras se han aplicado a casos reales en Kinshasa y Bandundu. / [CA] Quasi la meitat de la població mundial no té accés a energies com l'electricitat o el gas i han d'utilitzar forçosament biomassa per a cuinar, principalment llenya i carbó.

Amb un xicotet estalvi en el combustible que utilitzen aquestes estufes dels països sense accés a una altra mena d'energia, el resultat global és extraordinari. En el cas de la República Democràtica del Congo més del 80% de la població realitza les seues activitats culinàries utilitzant biomassa sòlida (llenya, carbó vegetal, etc.) Per a cuinar en les zones rurals i els extraradis de les grans ciutats s'utilitza la tradicional estufa de tres pedres (TCS-3P) i en les zones urbanes la tradicional estufa de carbó vegetal (TCS-C). El principal desavantatge d'aquesta pràctica és una combustió de baixa eficiència energètica, amb la conseqüència directa d'un consum excessiu de matèries primeres com a carbó i llenya i la corresponent desforestació. Aquests equips de cuina tradicionals emeten molts contaminants perjudicials per a la salut (CO i PM), així com i emissions que contribueixen al calfament global i al canvi climàtic (CO₂ i BC). En aquest treball proposem models per a millorar l'eficiència energètica utilitzant el model tradicional com a punt de partida, tal com ho utilitza la comunitat local. Per a les poblacions que viuen en condicions molt crítiques i precàries, s'han proposat "inserits de ceràmica" que poden fabricar-se i afegir-se a les estufes que utilitzen en l'actualitat. Aquests inserits poden actuar sobre el rendiment amb millores del 15%. S'ha proposat i analitzat una segona millora basada en la combustió natural de l'estufa de carbó ICS-C. El model més prometedor és l'estufa que utilitza el principi de micro gasificació de la biomassa. S'han dissenyat dos models d'aquesta estufa, el model (ICS-G1) amb un sol reactor de combustió i el model (ICS-G2) amb dos reactors de combustió, i s'han realitzat anàlisi de sostenibilitat amb aplicació directa a les comunitats locals. El model de micro gasificació proposat funciona amb un subministrament d'aire forçat amb una gran flexibilitat de variació de la potència de foc segons la mena de menjar a cuinar. El sistema de subministrament d'aire és proveït per un xicotet motor alimentat per energia solar amb autonomia proporcionada per una xicoteta bateria de liti recarregable. Els models de gasificació mostren importants avantatges en comparació amb el sistema tradicional, millor eficiència energètica, en necessitar menys de la meitat de llenya que amb la tradicional, reduccions dràstiques de les emissions contaminants i atmosfèriques, amb un estalvi d'emissions de CO₂ a la ciutat de Kinshasa estimades en 3405 kton/any i una reducció de quasi la meitat del temps dedicat a la preparació d'aliments. Aquestes estufes poden utilitzar tot tipus de combustibles sòlids, a més del carbó, es van realitzar assajos amb combustibles alternatius que provenen de residus agrícoles (BSW3) d'aquesta forma es limita la pressió exercida sobre els boscos a causa de l'ús de llenya per a cuinar. Els mètodes de prova utilitzats són la prova d'ebullició de l'aigua i la prova de cocció controlada, amb aquesta última es realitza una preparació d'aliments en un ambient controlat. Els resultats d'aquestes millores s'han aplicat a casos reals a Kinshasa i Bandundu. / [EN] Abstract Almost half of the world's population does not have access to energy such as electricity or gas and they have to use biomass for cooking, mainly firewood and charcoal. What in developed countries seems a luxury, in many others is an obligation, since there is no other alternative. With a small saving in the fuel used by these stoves in countries without access to other types of energy, the overall result is extraordinary. In the case of the Democratic Republic of the Congo, more than 80% of the population carries out their culinary activities using solid biomass (firewood, charcoal, etc.). The traditional stove is used to cook in rural areas and on the outskirts of large cities. three-stone TCS-3P and in urban areas the traditional TCS-C charcoal stove. The main disadvantage of this practice is low energy efficiency combustion, with the direct consequence of excessive consumption of raw materials such as coal and firewood and the corresponding deforestation. These traditional kitchen equipment emits many harmful pollutants for health (CO and PM), as well as emissions that contribute to global warming and climate change (CO2 and BC). In this work we propose models to improve energy efficiency using the traditional model as a starting point, as used by the local community. For populations living in very critical and precarious conditions, "ceramic inserts" have been proposed that can be manufactured and added to the stoves they use today. These inserts can act on performance with improvements of 15%. A second improvement based on the natural combustion of the ICS-C coal stove has been proposed and analyzed. The most promising model is the stove that uses the principle of microgasification of biomass. Two models of this stove have been designed, the ICS-G1 model with a single combustion reactor and the ICS-G2 model with two combustion reactors, and sustainability analyzes have been carried out with direct application to local communities. The proposed micro gasification model works with a forced air supply with great flexibility of variation of the fire power according to the type of food to be cooked. The air supply system is provided by a small motor powered by solar energy with autonomy provided by a small rechargeable lithium battery. The gasification models show important advantages compared to the traditional system, better energy efficiency, since it requires less than half as much firewood than with the traditional system, drastic reductions in pollutant and atmospheric emissions, with savings in CO2 emissions in the city of Kinshasa estimated at 3405 kton / year and a reduction of almost half the time spent on food preparation. These stoves can use all types of solid fuels, in addition to coal, tests were carried out with alternative fuels that come from agricultural residues (BSW3) in this way the pressure exerted on the forests due to the use of firewood for cooking is limited. The test methods used are the water boiling test and the controlled cooking test, with the latter a food preparation is performed in a controlled environment. The results of these improvements have been applied to real cases in Kinshasa and Bandundu. / Mulumba Ilunga, Ó. (2021).

Ancient lipids reveal continuity in culinary practices across the transition to agriculture in Northern Europe

Craig, O.E., Steele, Valerie J., Fischer, Anders, Hartz, S., Andersen, S.H., Donohoe, P., Glykou, A., Saul, H., Jones, D.M., Koch, E., Heron, Carl P. January 2011 (has links)
No / Farming transformed societies globally. Yet, despite more than a century of research, there is little consensus on the speed or completeness of this fundamental change and, consequently, on its principal drivers. For Northern Europe, the debate has often centered on the rich archaeological record of the Western Baltic, but even here it is unclear how quickly or completely people abandoned wild terrestrial and marine resources after the introduction of domesticated plants and animals at approximately 4000 calibrated years B.C. Ceramic containers are found ubiquitously on these sites and contain remarkably well-preserved lipids derived from the original use of the vessel. Reconstructing culinary practices from this ceramic record can contribute to longstanding debates concerning the origins of farming. Here we present data on the molecular and isotopic characteristics of lipids extracted from 133 ceramic vessels and 100 carbonized surface residues dating to immediately before and after the first evidence of domesticated animals and plants in the Western Baltic. The presence of specific lipid biomarkers, notably omega-(o-alkylphenyl)alkanoic acids, and the isotopic composition of individual n-alkanoic acids clearly show that a significant proportion ( approximately 20%) of ceramic vessels with lipids preserved continued to be used for processing marine and freshwater resources across the transition to agriculture in this region. Although changes in pottery use are immediately evident, our data challenge the popular notions that economies were completely transformed with the arrival of farming and that Neolithic pottery was exclusively associated with produce from domesticated animals and plants.

Earliest evidence for the use of pottery

Craig, O.E., Saul, H., Lucquin, A.J.A., Nishida, Y., Tache, K., Clarke, Leon J., Thompson, A., Altoft, D.T., Uchiyama, J., Ajimoto, M., Gibbs, K., Isaksson, S., Heron, Carl P., Jordan, P. January 2013 (has links)
No / Pottery was a hunter-gatherer innovation that first emerged in East Asia between 20,000 and 12,000 calibrated years before present (cal bp), towards the end of the Late Pleistocene epoch, a period of time when humans were adjusting to changing climates and new environments. Ceramic container technologies were one of a range of late glacial adaptations that were pivotal to structuring subsequent cultural trajectories in different regions of the world, but the reasons for their emergence and widespread uptake are poorly understood. The first ceramic containers must have provided prehistoric hunter-gatherers with attractive new strategies for processing and consuming foodstuffs, but virtually nothing is known of how early pots were used. Here we report the chemical analysis of food residues associated with Late Pleistocene pottery, focusing on one of the best-studied prehistoric ceramic sequences in the world, the Japanese Jomon. We demonstrate that lipids can be recovered reliably from charred surface deposits adhering to pottery dating from about 15,000 to 11,800 cal bp (the Incipient Jomon period), the oldest pottery so far investigated, and that in most cases these organic compounds are unequivocally derived from processing freshwater and marine organisms. Stable isotope data support the lipid evidence and suggest that most of the 101 charred deposits analysed, from across the major islands of Japan, were derived from high-trophic-level aquatic food. Productive aquatic ecotones were heavily exploited by late glacial foragers, perhaps providing an initial impetus for investment in ceramic container technology, and paving the way for further intensification of pottery use by hunter-gatherers in the early Holocene epoch. Now that we have shown that it is possible to analyse organic residues from some of the world's earliest ceramic vessels, the subsequent development of this critical technology can be clarified through further widespread testing of hunter-gatherer pottery from later periods.

Aquatic Resources in Foodcrusts: Identification and Implication

Heron, Carl P., Craig, O.E. January 2015 (has links)
No / Foodcrusts, the charred surface deposits on pottery vessel surfaces, provide a rich source of data regarding container function. This article reviews recent applications focusing on the detection of aquatic resources (marine and freshwater) in pottery vessels using a range of analytical approaches including bulk isotope measurements of carbon and nitrogen, lipid biomarker analysis, and compound-specific carbon isotope determinations. Such data can help to evaluate the presence of reservoir effects when undertaking radiocarbon dating of foodcrust samples. In particular, molecular and isotopic analysis can aid in the selection of suitable candidates for C-14 where it can be demonstrated that aquatic resources are unlikely to contribute to the residue. Prospects for compound-specific C-14 analysis of lipids in foodcrusts and ceramic-absorbed residues are also discussed.
