摘要： In producing C2-C4 olefins, in particular propylene, from an educt mixture containing steam and oxygenates, such as methanol and/or dimethyl ether, the educt mixture is reacted in a reactor on a catalyst to a reaction mixture comprising low-molecular olefins and gasoline hydrocarbons, which in a first separating device is separated into a mixture rich in C5− olefins, a mixture rich in C5+ gasoline hydrocarbons, and an aqueous phase. To increase the yield of propylene the mixture rich in C5+ gasoline hydrocarbons is supplied to a second separating device, in which the aromatics contained in the mixture are separated. The residual stream largely free from aromatics is at least partly recirculated to the reactor.

摘要： For producing synthetic fuels, an educt mixture containing steam and oxygenates, such as methanol and/or dimethyl ether, is converted to olefins on a catalyst in a first process stage, and this olefin mixture then is divided in a separating means into a stream rich in C1-C4 hydrocarbons and a stream rich in C5+ hydrocarbons. The stream rich in C5+ hydrocarbons is divided into a stream rich in C5 and C6 hydrocarbons and a stream rich in C7+ hydrocarbons, wherein the stream rich in C5 and C6 hydrocarbons is at least partly subjected to an etherification with methanol. The ethers thus obtained are admixed to the gasoline product stream.

摘要： A process produces dimethyl ether (DME) from methanol (MeOH). The process includes charging a feed mixture consisting of raw MeOH and a process-internally obtained return flow substantially consisting of unconverted MeOH and reaction water to an MeOH column. The feed mixture is evaporated in the MeOH column to form a first distillate substantially consisting of vaporous MeOH. The first distillate is supplied to a reactor and the MeOH is converted to DME by splitting off water in the reactor so as to form a reaction mixture. The reaction mixture is withdrawn from the reactor, charged to a mixture column and separated into a bottom product substantially consisting of water and a second distillate substantially consisting of DME and MeOH. The second distillate is separated in a DME column into a third distillate substantially consisting of DME, a bottom product consisting essentially of water-poor MeOH, and uncondensable gases discharged overhead. The bottom product is either supplied to a top of the MeOH column or mixed with another bottom product withdrawn from a forerun column.

摘要： In a process for producing synthetic fuels from an educt mixture containing hydrogen and oxygenates, such as methanol and/or dimethyl ether, the educt mixture is reacted on a catalyst in a first process stage to obtain a hydrocarbon product containing olefins with preferably 2 to 8 carbon atoms. In a second process stage the hydrocarbon product is oligomerized to long-chain olefins, from which gasoline and Diesel products are obtained. The hydrocarbon product obtained in the first process stage is separated into a liquid phase and a gaseous phase. The gaseous phase is supplied to the second process stage. The liquid phase is separated into a mixture rich in C6− hydrocarbons and a mixture containing C7+ hydrocarbons and aromatics. The mixture rich in C6− hydrocarbons is supplied to the second process stage. The mixture containing C7+ hydrocarbons −+ and aromatics can be admixed to the gasoline product for quality improvement.
