Previous issue date: 2014-03-21 / The oily sludge is a complex mix of hydrocarbons, organic impurities, inorganic
and water. One of the major problems currently found in petroleum industry is
management (packaging, storage, transport and fate) of waste. The nanomaterials
(catalysts) mesoporous and microporous are considered promising for refining and
adsorbents process for environment protection. The aim of this work was to study the
oily sludge from primary processing (raw and treated) and vacuum residue, with
application of thermal analyses technique (pyrolysis), thermal and catalytic pyrolysis
with nanomaterials, aiming at production petroleum derived. The sludge and vacuum
residue were analyzed using a soxhlet extraction system, elemental analysis, thin layer
chromatography, thermogravimetry and pyrolysis coupled in gas chromatography/mass
spectrometry (Py GC MS). The catalysts AlMCM-41, AlSBA-15.1 e AlSBA-15.2
were synthesized with molar ratio silicon aluminum of 50 (Si/Al = 50), using
tetraethylorthosilicante as source of silicon and pseudobuhemita (AlOOH) as source of
aluminum. The analyzes of the catalysts indicate that materials showed hexagonal
structure and surface area (783,6 m2/g for AlMCM-41, 600 m2/g for AlSBA-15.1, 377
m2/g for AlSBA-15.2). The extracted oily sludge showed a range 65 to 95% for organic
components (oil), 5 to 35% for inorganic components (salts and oxides) and
compositions different of derivatives. The AlSBA-15 catalysts showed better
performance in analyzes for production petroleum derived, 20% increase in production
of kerosene and light gas oil. The energy potential of sludge was high and it can be used
as fuel in other cargo processed in refinery / A borra oleosa (BO) de petr?leo ? uma mistura complexa de hidrocarbonetos,
impurezas org?nicas, inorg?nicas e ?gua. Um dos grandes problemas encontrados
atualmente na ind?stria de petr?leo ? o gerenciamento (acondicionamento,
armazenamento, transporte e destino) de res?duos. Os nanomateriais (catalisadores)
mesoporosos e microporosos s?o considerados promissores em processos de refino de
petr?leo e como adsorventes para prote??o ambiental. O objetivo deste trabalho foi
estudar a BO de petr?leo oriunda do processamento prim?rio (bruta e tratada) e res?duo
de v?cuo, com aplica??o de an?lise termogravim?trica, t?cnica de pir?lise t?rmica e
catal?tica com nanomateriais, visando a produ??o de derivado de petr?leo. As borras
extra?das em um equipamento soxhlet foram analisadas por an?lise elementar,
cromatografia em camada fina, termogravimetria (TG) e pir?lise acoplado a um
cromatogr?fico gasoso/espectro de massa (Py-GC/MS). Os catalisadores AlMCM-41 e
AlSBA-15 foram sintetizados com uma raz?o molar de s?licio/alum?nio de 50 (Si/Al =
50), usando tetraetilortossilicato (TEOS) como fonte de sil?cio e pseudobuhemita
(AlOOH) como a fonte de alum?nio. Os catalisadores indicam que os materiais
apresentaram estrutura hexagonal, ?rea espec?fica de 783,6 m2/g para o AlMCM-41, 600
m2/g para o AlSBA-15.1 e 377 m2/g para o AlSBA-15.2). A BO extra?da apresentou de
65 a 95% de componentes org?nicos (?leo), de 5 a 35% de componentes inorg?nicos
(sais e ?xidos) e diferentes composi??es dos derivados. Os catalisadores tipo AlSBA-15
apresentaram melhor desempenho na obten??o dos derivados de petr?leo, aumentando
em 20% a produ??o de querosene e gas?leo leve. O potencial energ?tico da BO foi
elevado, pois ela pode ser utilizada como combust?vel e processada com outras cargas
pesadas do petr?leo para a produ??o de diferentes derivados de petr?leo
