Abstract

An integrated process for converting methanol and other lower molecular weight oxygenates to gasoline and distillate range liquid hydrocarbons and ethene is disclosed. When it is desirable to increase ethene yield, an auxiliary methanol-to-olefins (MTO) fixed bed reactor unit is activated in conjunction with a continuously operated primary MTO fluidized bed reactor.
