HYDROGEN REJECTION IN METHANOL TO HYDROCARBON PROCESS

摘要

The present invention relates to a process for production of hydrocarbons comprising the following steps: converting a feed stream comprising alcohols, ethers or mixtures thereof over a metal-containing zeolite based catalyst, active in dehydrogenation of hydrocarbons, in a conversion step, thereby obtaining a conversion effluent, separating said effluent to obtain an aqueous process condensate stream, a liquid hydrocarbon stream and a gaseous stream, removing part of the hydrogen formed in the conversion step, and recycling at least part of the gaseous and/or liquid hydrocarbon stream to the conversion step.
