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, 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 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.
