Outline of Final Research Achievements

Zeolite containing mesoporous SiO2-Al2O3 catalysts with three layered-hierarchical structures were prepared using the gel skeletal reinforcement methods. Catalytic cracking of soybean oil was performed using Curie point pyrolyzer (CPP) which was demonstrated as a promising method for estimation of processing of heavy hydrocarbon resources. It was found that the multi/single branch ratios and conversion were improved with increasing hierarchical structure because the catalysts had the larger space.
The gel skeletal reinforcement (GSR) method was developed to prepare silica-aluminas (GSR-SA) with different sizes of large mesopores. The effects of mesopore sizes of catalysts on catalytic cracking of vacuum gas oil (VGO) and atmospheric residue (AR) by CPP method were investigated using the mixed catalysts with zeolite and GSR-SA. 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.
