Prolonging zeolite catalyst life in methanol conversion to gasoline by disposing of exothermic reaction heat

摘要

A method for effecting chemical reactions of aliphatic hetero compounds comprising alcohols, halides, mercaptans, sulfides, amines, ethers and carbonyl compounds with a fluidized crystalline zeolite catalyst and regeneration of a portion of the catalyst used in the fluid catalyst operation is described. Catalyst recycle to each of the catalyst contact zones is particularly employed.
