Patent number: 9573863Abstract: In the production of low-molecular olefins, in particular of ethylene and propylene, an educt stream (O) containing at least one oxygenate and an educt stream (C) containing at least one C4+olefin are simultaneously converted in at least one identical reactor on an identical catalyst to obtain a product mixture (P) comprising low-molecular olefins and gasoline hydrocarbons. The ratio (V) of oxygenates in the educt stream (O) to C4+ olefins in the educt stream (C) here is 0.05 to 0.5 and is calculated according to the following formula: V = ? j ? k oxygenate - j * n oxygenate - j ? i ? k olefin - i * n olefin - i + ? j ? k oxygenate - j * n oxygenate - j with: koxygenate-j: carbon number of the oxygenate j noxygenate-j: molar flow rate of the oxygenate j kolefin-i: carbon number of the olefin i nolefin-i: molar flow rate of the olefin i.Type: GrantFiled: February 7, 2012Date of Patent: February 21, 2017Assignee: Lurgi GmbHInventors: Gerhard Birke, Hermann Bach

Patent number: 9505684Abstract: A process and a plant for producing an olefin stream from a hydrocarbon mixture feed stream, wherein the olefin stream is depleted as regards its content of oxygen-containing organic compounds (oxygenates) as compared to the feed stream. The hydrocarbon mixture feed stream is charged to a separation column operated by a thermal separation process, for example to a distillation column, wherein a material stream enriched in oxygenates is withdrawn via a side outlet and removed from the process. The process according to the invention is particularly useful for processing the product streams obtained in the olefin synthesis by an OTO process.Type: GrantFiled: April 21, 2011Date of Patent: November 29, 2016Assignee: AIR LIQUIDE GLOBAL E&C SOLUTIONS GERMANY GMBHInventors: Hermann Bach, Thomas Renner, Martin Rothaemel, Michael Wilken

Publication number: 20160046542Abstract: There is proposed a process for producing short-chain olefins by conversion of oxygenates in a multi-stage fixed-bed reactor (OTO reactor) with reaction zones each operated adiabatically, in which the individual stages or reaction zones are covered with beds of a granular, form-selective zeolite catalyst which previously has been subjected to a steam pretreatment in an external, isothermally or quasi-isothermally operated steam pretreatment reactor. By means of the external steam pretreatment according to the invention, higher lifetimes of the catalyst used are obtained as compared to a steam pretreatment in the OTO reactor. The availability of the OTO reactor for the olefin production is increased.Type: ApplicationFiled: March 20, 2014Publication date: February 18, 2016Inventors: Stephane HAAG, Holger DROPSCH, Theis OHLHAVER, Hermann BACH, Martin ROTHAMEL

Patent number: 8884074Abstract: 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.Type: GrantFiled: November 19, 2009Date of Patent: November 11, 2014Assignee: Air Liquide Global E&C Solutions Germany GmbHInventors: Bernd Ahlers, Gerhard Birke, Harald Koempel, Hermann Bach, Martin Rothaemel, Waldemar Liebner, Walter Boll, Veronika Gronemann

Patent number: 8785708Abstract: In a process for the preparation of C2- to C4-olefins, a feed stream comprising oxygenates and steam is passed through at least one fixed-bed zone comprising zeolite catalyst, where the oxygenates are converted catalytically into olefins with high selectivity for lower olefins, and the reaction mixture leaving the fixed-bed zone is separated into a first product stream comprising C2- to C3-olefins and inert gas components, at least one second product stream comprising C4+-olefins, and a third product stream consisting of aqueous phase. In order to improve the yield of lower olefins, the aim is to regulate the temperature of the catalytic reaction in accordance with a target temperature value in the range from 440 to 520° C. specified for the reaction mixture exiting the fixed-bed zone by means of a supplementary stream consisting of olefins and inert gas components fed into the feed stream.Type: GrantFiled: February 28, 2006Date of Patent: July 22, 2014Assignee: Lurgi AGInventors: Martin Rothaemel, Walter Boll, Gerhard Birke, Harald Koempel, Waldemar Liebner, Hermann Bach
