Abstract: A novel type of composite ZSM-5 zeolite/asbestos material(Z-5-A), whose ZSM-5 zeolite was embedded in the crystalline asbestos fibers as a substrate, was synthesized hydrothermally at 160℃. The reactants were asbestos as a part of silicon reesource, water glass, aluminium sulphate, amine and water. Z-5-Awas charactrized using the methods of XRD, SEM and adsorption and its composition was analysed. The results showed that H-type composite ZSM-5 zeolite/asbestos material(H-Z-5-A) was different from H-ZSM-5 zeolite and there were both acid and base sites on the surface.The H-Z-5-A can be used as a catalyst, on which the selectivity of light alkene in the methanol conversion was superior to that on H-ZSM-5 catalyst. On ZnCr/H-Z-5-Acatalyst,which was a mixture of H-Z-5-Awith Zn-Cr catalyst, the coke deposits, conversion of CO and HC selectivity of the gasoline synthesized from water gas by one-step method were also superior to those -on the Zn-Cr/HZSM-5 catalyst.
Key words: Composite ZSM-5 zeolite/asDestos material, Methanol conversion catalyst, Synthetic gasoline catalyst
