英文摘要The phosphorus-modified ZSM-5/ZSM-11 intergrowth zeolites has been used for the catalytic conversion of methanol to hydrocarbons. As evidenced by MAS NMR and NH(3)-TPD, the modification by phosphorus leads a distinct decrease of the Bronsted acid sites and the acid strength of the catalysts in comparison with the parent ZSM-5/ZSM-11, which causes a dramatic improvement of the selectivity towards propylene. At 400 degrees C, the ratio of propylene to ethylene can reach about 8.0. A comparison with the conventional ZSM-5 zeolite has been also carried out in the present study.
