PROCESS FOR THE PRODUCTION OF ALCOHOLS

摘要

The present invention provides a process for the production of alcohols, which process comprises the steps of: (a) reacting an oxygenate and/or olefinic feed in a reactor in the presence of a molecular sieve catalyst to form an effluent comprising olefins, comprising propylene; (b) separating the effluent comprising olefins as obtained in step (a) into at least a first olefinic product fraction comprising propylene and a second olefinic product fraction; (c) subjecting at least part of the first olefinic product fraction as obtained in step (b) to a hydroformylation process to form aldehydes; (d) hydrogenating at least part of the aldehydes as obtained in step (c) to form alcohols; (e) separating at least part of the alcohols as obtained in step (d) into at least a first product fraction of alcohols and a second product fraction of alcohols; and (f) recycling at least part of the first or second product fraction of alcohols to step (a).
