摘要： A process for producing short-chain olefins by conversion of oxygenates in a multi-stage fixed-bed reactor, in which the individual stages for reaction zones are covered with beds of a granular, form-selective zeolite catalyst and the feed mixture containing oxygenates is added distributed over the reaction stages. An increase of the availability of the fixed-bed reactor for the olefin production with the same or an increased yield of short-chain olefins is achieved in that one or more reaction zones are charged with a distinctly reduced mass flow of the feed mixture containing oxygenates, wherein the reduced mass flow fraction is distributed over other reaction zones.

摘要： A process for producing olefins from oxygenates includes the following steps: (i) heterogeneously catalyzed conversion of at least one oxygenate to a stream containing propylene, aromatics and cyclic olefins, (ii) at least partial hydrogenation of the aromatics and cyclic olefins to naphthenes, and (iii) at least partial recirculation of the naphthenes into the heterogeneously catalyzed conversion.

摘要： The present invention relates to a plant and a process for producing propylene at least one oxygenate, comprising a reactor for converting the reactant mixture into a product mixture which comprises propylene and also aliphatic and aromatic C5+ hydrocarbons, at least one distillation column for removing a C5+ stream, the C5+ stream comprising at least 90 wt % of the aliphatic and aromatic C5+ hydrocarbons of the product mixture, an extractive distillation column for separating the C5+ stream into an aromatics stream and an aliphatics stream, the aliphatics stream comprising at least 90 wt % of the aliphatics of the C5+ stream, and the aromatics stream comprising at least 90 wt % of the aromatics of the C5+ stream, and an aliphatics recycle line for at least partial recycling of the aliphatics stream to the reactor. According to the invention, an aromatics recycle line is provided which returns the aromatics stream at least partially as extractant into the extractive distillation column.
