摘要： A process for converting methanol and/or dimethyl ether to olefins at moderate temperature and atmospheric pressure comprising contacting the feed with an alumina crystalline zeolite catalyst designated as ZSM-48. The olefins formed can then be converted to a low-durene gasoline over ZSM-5 type catalysts under conventional aromatizing conditions or to a distillate boiling above the gasoline range.
