Abstract

The present application relates to a process for production of hydrocarbons comprising the steps of: converting a feed stream comprising alcohols, ethers or mixtures hereof over a Zn-containing zeolite based catalyst wherein Zn is at least partly present as ZnAlO, 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.
