Preparation of WO3/TS-1 Molecular Sieve and the Study on the Epoxidation Properties of Catalytic Cyclopentane
A series of WO3/TS-1 zeolites were prepared by wet impregnation using hierarchical TS-1 as a carrier.SEM,TEM,XRD,IR,UV-Vis,XPS,BET,ICP and other analytical methods were used to characterize the structure,morphology and properties of the catalyst.The catalytic performance of this series of zeolite in the epoxidation of cyclopentane was investigated.The best catalytic performance was obtained when the mass fraction of W was 4％.After the catalyst was cycled four times,the selec-tivity and yield of 1,2-epoxycyclopentane were keeped at 68.7％and 55.5％.
