Tetraethylorthosilicate (TEOS) was used not only as a precursor of silica, but also as an agent which reinforces the skeleton of silica-gel to prepare an aerogel and resultant silica and silica-alumina with large pore size and pore volume. In this gel skeletal reinforcement (GSR), the strength of silica aerogel skeleton was enhanced by aging with TEOS/2-propanol mixture to prevent the shrinkage of pores. In shit work, a Curie point pyrolyzer was introduced to estimate catalytic cracking of heavy oils, vacuum gas oil and atmospheric residue using the mixed catalysts of zeolite and silica-alumina prepared by the GSR method. The conversions of VGO and AR using the mixed catalysts were higher than those of zeolite single and increased with increasing the pore size of silica-alumina.
