    Abstract: A methanol conversion process comprises contacting a feedstream comprising methanol, optionally with dimethyl ether or other oxygenates with a catalyst comprising a physical mixture of a molecular sieve, preferably an intermediate or small pore size zeolite such as an MFI zeolite, with a basic metal oxide to provide extended catalyst cycle life by reducing the incidence of coke formation. The process may be applied to the methanol-to-gasoline (MTG), methanol to distillate (MOD), methanol-to-olefins (MTO), methanol-to-chemicals (MTC) and combination processes such as the MTO/OCP Process.
