WO3-ZSM-5/MCM-41催化剂的合成

及其催化氧化脱硫研究

Abstract

Abstract: A new micro-mesoporous ZSM-5/MCM-41 was prepared with ZSM-5 zeolite（treated in NaOH solution） as the source of silicon.The ZSM-5/MCM-41 was characterized by XRD，TEM，and N2 adsorption and desorption.In addition，its hydrothermal stability was investigated.The results showed that the composite molecular sieve ZSM-5/MCM-41 had the structure of both microporous ZSM-5 and mesoporous MCM-41，and had the stronger hydrothermal stability than the mesoporous molecular sieve MCM-41.Applied to thiophene/octane model oil system，after loading 10% mass fraction of WO3，the WO3-ZSM-5/MCM-41（mass fraction of 10%） showed good catalytic performance when the oxidant was H2O2，and the desulfurization rate could reach 93.6%.

Key words: ZSM-5, alkali treatment, composite molecular sieves, catalytic oxidation desulphurization
