The reaction of methanol on T-type zeolites has been studied at 400 deg C in a flow reactor .The results demonstrate the influence of decationization and dealumination of zeolites on catalytic lifetimes (maximum 4 h).To reduce the deactivation of HT zeolites by coke formation, Ni- and Pt-exchanged samples have been used, and the reaction has been studied in the presence of hydrogen.The deactivation of Pt-HT is much slower than that of HT but only paraffinic hydrocarbons are produced.Observations by infrared spectroscopy of the conversion of deuterated methanol in the 20-400 deg C region are embodied in a mechanism of propylene formation invoking dimethyl ether, methoxy groups and zeolite-T hydroxy groups.
