The results indicated that the synthesized sample not only has a composite structure with ZSM-5 and silica gel, but also retains the shape of silica gel microsphere. To obtain detailed information on the rules of synthesized chemistry, the effects of SiO2/Al2O3 of initial gel, H2O/SiO2, BuNH2/SiO2, OH /SiO2, crystallization time and crystallization temperature on ZSM-5 crystallinity were systematically studied. The composite materials were tested in a micro fixed-bed reactor, using Daqing Vacuum Gasoline Oil (VGO) as the feedstock. The results indicated that the composite structure zeolite yields more light olefins and has good selectivity to light olefins. %K composite molecular sieves %K ZSM-5 %K silica gel %K in-situ synthesis %K light olefins
