Preparation of Y Zeolite-Based Catalysts and their Catalytic Cracking Performances of Venezuelan Heavy Oil

Abstract:

Five kinds of modified Y zeolite-based fluid catalytic cracking (FCC) catalysts were prepared. The N₂ adsorption desorption and NH₃ temperature-programmed-desorption (NH₃-TPD) were used to investigate the pore structure and acidic properties of the catalysts. The effects of pore structure and acidic properties of catalysts on the catalytic cracking performance of Venezuelan heavy oil were carried out using an advanced cracking evaluation unit. The results of N₂ adsorption desorption and NH3-TPD show that CAT-A and CAT-B catalysts with rundle pore distribution have a similar pore sizes and acid_{Subscript text}_{Subscript text}ic properties. The catalytic cracking results show that the acidic properties and the pore distribution of the catalysts have obvious effects on the conversion and product distribution. The light oil yield and total liquid oil yield can reach 58.75wt% and 73.83 wt%, respectively, under reaction temperature of 520°C.
