Abstract
To increase heavy oil conversion by hydrocracking, the larger pore opening mesoporous materials with enhanced acidity and hydrothermal stability are required. A series of mesoporous Al-SBA-15 was studied in acid-free and different HCl concentration solutions with various initial SiO2/Al2O3 molar ratio. The final product samples were characterized with N2 adsorption, SAXS/XRD, NH3-TPD, TEM, 28Si NMR, and 27Al NMR. The results concluded that the acid-free and weak acidic medium favor the formation of the Al-SBA-15 with better textual properties, higher acidity, and higher wall-thickness. A considerable amount of Al was present in the tetrahedral form.
