摘要: The mesoporous material AlSBA-15 with Si/Al molar ratio of 25 was synthesized by the hydrothermal method and characterized X-ray diffraction nitrogen adsorption. This is a promising in field catalysis, particularly for petroleum refining, since their mesopores facilitate accessibility large hydrocarbon molecules to active sites AlSBA-15, producing light hydrocarbons. In order evaluating catalytic activity sample ca. 10 % mass this solid physically mixed atmospheric residue (ATR) heated thermobalance from room temperature up 900 °C, under atmosphere. From TG curves, it observed reduction onset temperature, when used as catalyst degradation process ATR. kinetic model proposed Ozawa–Flynn–Wall yielded some parameters determine apparent activation energy degradation, evidencing efficiency material, there decrease degradation. ATR alone also pyrolysis reactor coupled gas chromatograph spectrometer (Py-GC/MS). chromatograms, an increase yield hydrocarbons range gasoline diesel derived process. These results are due combination mesoporosity acidity application constituents
