In order to convert a large molecule of soybean oil, ZSM-5 zeolite-containing silica-aluminas with three layered micro-meso-meso-structure were developed. In this method, zeolite-containing two layered silica-aluminas initially prepared were combined with silicas having very large mesopores prepared by the gel skeletal reinforcement. The three-layered structure was confirmed by pore size distribution...
Silica-aluminas with very large mesopores were prepared by the gel skeletal reinforcement technique and were combined with microporous zeolite, resulting in the formation of catalysts with hierarchical structure. Catalytic cracking of vacuum gas oil (VGO) and atmospheric residue (AR), specifically the influence of the pore size of the catalysts on the reactivity of VGO and AR, was investigated using...
