RESUMO:

The oily sludge presents a complete aggregate of hydrocarbons, organic and
inorganic impurities, and water. One of the main bottlenecks currently found in oil
industry it's the manegement (packaging, storage, transportation and destination) of
waste. The nanomaterials (catalysts) mesoporous and microporous are considered
promissing in oil refining processes and as absorvents to enviromental protection. The
focus of this work was study de oily sludge from primary processing (treated), with
applications of thermal degradation and thermocatalytic with nanomaterials, aiming the
production of oil derivates. The catalyst NaY was sintetized with a silica/aluminum molar
ratio of 50 (Si/Al = 1,5), using sodium silicate (Na2SiO3) as source of silicon e sodium
aluminate (NaAlO2), as the aluminum source and, posteriorly was done a ion exchange
to obtain its acid form - HY. The samples of the nanostructured materials by
thermogravimetric analysis (TG/DTG), X-ray diffraction (DRX), scanning electro
micorscopy (SEM), absorption spectroscopy in the infrared region with Fourier transform
(FT-IR). The characterizations showed that the synthesized materials resulted in a
nanostructured catalyest according to the existent literature. The thermal and catalytic
degradation of the oily sludge was performed in the temperature ranges of 100, 200, 300,
400 and 500 °C, varying with time of 0 to 60 min to each temperature. The curves
obtained through degradation showed a faster deterioration of oily sludge when there ir a
presence of catalyst on the midst. These datas were corroborated by the activation energy and were studied by Arrhenius parameter, where was possible to observe the activation energy to thermal and thermo-catalytic degradation of the oily sludge.
