The gel skeletal reinforcement (GSR) method was developed to prepare silicas with different sizes of large mesopores. Using silica-aluminas prepared with GSR-silicas by the conventional impregnation method, the mixed catalysts with zeolite was prepared. The effects of mesopore sizes of catalysts on catalytic cracking of vacuum gas oil (VGO) and atmospheric residue (AR) by Curie point pyrolyzer were investigated using the mixed catalysts. It was found that the conversions of VGO increased with increasing pore size of catalysts while the effect of pore size on the conversion of AR was only slight. It was thought that the effect of diffusion would be too small to appear because AR includes more than 50% of heavy fraction with boiling point higher than reaction temperature 500℃.
