Abstract: The present invention provides a process for the production of aldehydes and/or 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) separating at least part of the aldehydes as obtained in step (c) into at least a first product fraction of aldehydes and a second product fraction of aldehydes; and (e) hydrogenating at least part of the aldehydes in the first and/or second product fraction of aldehydes as obtained in step (d) to form a first product fraction of alcohols and/or a second product fraction of alcohols; (f) recycling at least part of the first and/or second product fraction of alcohols obtained in step (e) to step (a).

Abstract: The invention relates to a process for preparing lower olefins from an oxygenate, the process comprising subjecting C4 hydrocarbons obtained in an oxygenate-to-olefins conversion step to extractive distillation to obtain a stream enriched in unsaturated C4 hydrocarbons comprising isobutene and n-butenes, and a stream enriched in saturated C4 hydrocarbons; converting the isobutene in the stream enriched in unsaturated C4 hydrocarbons into an alkyl tertiary butyl ether to obtain an isobutene-depleted unsaturated C4 hydrocarbon stream and alkyl tertiary-butyl ether; and recycling at least part of the isobutene-depleted unsaturated C4 hydrocarbon stream and/or at least part of the alkyl tertiary-butyl ether, optionally after conversion into tertiary butanol and/or isobutene, to the oxygenate-to-olefins conversion step.
