摘要：

The conversion of methanol into hydrocarbons over ZSM-5 zeolites shows autocatalytic nature. Thus, the hydrocarbon yields from methanol or dimethyl ether over ZSM-5(SiO2/Al2O3 = 2—84) increase abruptly by raising the reaction temperature from 280—300 °C. The temperature of the jump depends on the SiO2/Al2O3 ratio of the zeolites. The active sites for methanol conversion are poisoned by pyridine, but not by hydrogen chloride. © by Akademische Verlagsgesellschaft
