This thesis deals with the energy security of Israel in contemporary context of regional tension. The paper further examines the factors, which influence the energy security, possible threats and perspectives, which could lead to increased energy independence of the country. The thesis also elaborates on the new trends in the field of natural gas exploitation in Israel.

The study works with the paradigm of energy security of supply in the context of three Central Asian republics; Kazakhstan, Turkmenistan and Uzbekistan. It focus on the relations related to gas and oil. The subjects are analyzed from the point of their own energy strategy, institutions' efficiency as well as position in the energy market. The analysis deals with the main external actors; Russia, China and European Union. A great stress is laid on the evolution in gas and oil trading and the energy infrastructure in the region. Problems of relation between energy, security and politics are included. I try to cover the main trends in the gas and oil market and put them in the context of Central Asia. My conclusions limit the popular scheme of russian dominance and stress the growing cooperation with China, in contrast to EU. However, the growing interconnection of the euroasian gas market is also very important.

This thesis deals with the design of the equipment and documentation for the design of equipment for the removal of volatile organic compounds (VOC) and carbon monoxide (CO) by catalytic oxidation and the selection of appropriate technological conditions for this technology. Introduction is devoted to familiarization with the field of the catalytic oxidation, used catalysts, catalyst supports and their active components. Advantages and disadvantages of the use of catalytic oxidation versus thermal incineration are outlined and currently applicable legislative terms for VOC and CO emissions are listed. In the next part of the thesis the fundamental mathematical tools and research findings available for catalytic reactor model designed primarily for monolithic catalysts are summarized. Presented kinetic model considers continuous reactor with plug flow of gas and adiabatic heating by oxidation reactions corrected for the heat loss of the reactor. The next chapter discusses the design of the new prototype of the catalytic oxidation pilot plant (i.e. the reactor incl. peripherals) primarily intended for monolithic catalysts and bulk catalysts in the form of the fixed bed. The basis for the design and sizing are material and energy balances in the ChemCAD for different intended use of the unit, from which boundary conditions of the unit operating parameters arises. Pilot plant has been designed and built, functionality tests was scheduled also with consecutive obtaining of experimental data not only for the reactor kinetic model. Results of the model for the catalytic combustion were in good agreement with measured data. The next part includes two industrial case studies of the catalytic oxidation process usage for the chemical industry. In particular it was dealt with a replacement of the non-catalytic combustion for the catalytic for VOC abatement from chemical production plants off-gas streams of the company Momentive Specialty Chemicals in Sokolov and German city Leuna. These case studies have brought many valuable experimental and technological knowledge from long-term pilot tests and also verification of design concept, thanks to which it was later possible to design a pilot unit for removal of pollutants in premises of NETME Centre and among other to economically evaluate the usage of catalytic oxidation for the off gas cleaning, in comparison with traditional combustion, in two completely different individual cases. This information was valuable and necessary for the verification of theoretical assumptions of the thesis on specific conditions of two different industrial productions. Based on acquired practical experience and theoretical background, guidelines for designing of devices for VOC and CO removal in the industry were developed.

This diploma thesis deals with impurities in waste gases and syngas. Those gases usually have low heating value and contain impurities which are the main issue of those gas fuels. Waste gases and syngas can replace natural gas after right gas treatment. First part is theoretical. It starts with description of biomass and gasification technology. Then the waste gases are described – their origin and usual composition. Next part is dedicated to impurities and is followed by impurities treatment technologies. For removing of almost every type of impurity wet scrubber can be used which is described in detail in following part. There are other types of gas cleaning technologies, so they are described too but not in such detail as wet scrubber. In second part the wet scrubber is designed, and its function is tested by cleaning syngas from fluidized-bed gasifier called Biofluid. During gas cleaning in wet scrubber the influence of water temperature on efficiency of tar removal is examined.

The aim of this diploma thesis is to design a gas boiler for blast furnace gas combustion. At the beginning is performed stoichiometry of the used fuel to determine the optimal amount of combustion air and the actual amount of flue gas. Subsequently is determined the overall efficiency, together with heat and steam power of the boiler. The main part of the thesis is focused on the design of the combustion chamber and the dimensioning of heat exchange surfaces. At the end of the thesis are performed hydraulic and aerodynamic calculations to determine the pressure loss on the side of the working medium and flue gas. Drawing documentation can be found in attachments.

This master’s thesis deals with the process of biomass gasification using mixture of CO and O2 as gasification agent. First part describes the gasification process itself, used devices, gasification medium and its influence on the generated gas. Following section covers the experimental part of the work, which is focused on change properties of the generated gas using different ratios of CO2, O2, H2O and air in the gasification mixture. This part also includes processing and evaluation of the results.

The aim of this thesis is a draft of a gas steam boiler with steam output of 200 t/h. The first part of the paper provides stoichiometric calculations, then there are calculations of the dew point, boiler efficiency and the amount of gas. After that, calculations and a draft of the combustion chamber are carried out and then heat balances are drafted. In the following text, geometric properties of individual heat exchanging surfaces are drafted. At the end, there are control calculations. This thesis contains a blueprint of the gas steam boiler.

This thesis inquire into experimental decomposition of freon R-22 (CHClF2 - chlorodifluorometan) for different process conditions, by the help of pilot experimental unit in heavy laboratories DEPARTMENT of process and enviromental engineering Brno. This unit can decomposition waste gas, as the case may be combustion gas by the thermic oxidation or catalytic oxidation. Ground was in theoretical research, in which had been executed decomposition of freon R-22 in laboratory. In terms of experimental work were to be execution states for decomposition of freon R-22, next will be decomposition of freon R-22 by catalytic oxidation on catalyst Pt/Al2O3 and consequently this experiment will be analyse. Part of this thesis is exploration of facts basic way to decomposition of freon R-22, accounting of experimental unit and discussion of results.

The subject of the diploma thesis is an optimization of a heating system of a basic school Budisov, Czech Republic. The objective of the thesis is to design a change of the fuel basis of the heating system. The designed changes of heating system are compared with the current state with respect to both, technical and economical aspects. The known values of fuel consumption in the last seven year period and the heating power of fuel are considered. For the comparison of the complexity of the proposed change of the heating system the realization and recovery of investment are the main factors.

Proposed diploma work provides capture efficiency measurements of generated pollution captured by reinforced slot exhaust system in modification with work bench using tracer gas method. There are shown results of capture efficiency for traditional exhausting (no radial air added) and reinforced exhausting (using radial air supply effect) in this work. This study also conatins the comparison and discusion of obtained measurement results with measurement errors and uncertainties.
