Abstract:
P modified ZSM-5/aluminophosphates composite zeolite (wP-ZSM-5/AlPO4-m) was obtained by NH4H2PO4 modification of ZSM-5/AlPO4-m and characterized by XRD, N2 adsorption-desorption, NH3-TPD, FT-IR and so on. The effects of P loaded amount in wP-ZSM-5/AlPO4-m and the reaction conditions, reaction temperature and space velocity, on methanol conversion and product selectivity of MTP were investigated. It was confirmed that the surface area, acid strength and acid amount of wP-ZSM-5/AlPO4-m were effectively regulated by P modification, and the maximum ratio of B acid and L acid reached 3.03 in 3%P-ZSM-5/AlPO4-m, which had the best catalytic activity and stability at the reaction temperature of 500°C and MHSV of 1 h-1. The conversion rate of methanol, selectivity of propylene, molar ratio of propylene and ethylene remained around 100%, 50% and 5, respectively, when the reaction continued for 73 h.
