Patent number: 10252250Abstract: A process of producing a catalyst based on pentasil-type crystalline aluminosilicate is described, including the steps of (a) treating hydrous aluminum oxide with an aqueous, acid-containing medium, (b) mixing the hydrous aluminum oxide treated with aqueous, acid-containing medium from step (a) with an H-zeolite and (c) calcining the mixture obtained in step (b). In addition, a catalyst is disclosed which is obtained by such a process, as well as its use in CMO and OTO processes.Type: GrantFiled: July 8, 2011Date of Patent: April 9, 2019Inventors: Gotz Burgfels, Manfred Frauenrath, Sven Pohl, Martin Rothamel, Stephane Haag

Patent number: 9511361Abstract: A catalyst containing a pentasil-type alumosilicates and a binder, in the form of spheres having an average diameter between 0.3 and 7 mm, wherein the BET surface area of the catalyst ranges from 300 to 600 m2/g. Also disclosed is a method for producing the catalyst, wherein primary crystallites of the aluminosilicate having an average diameter of at least 0.01 ?m and less than 0.1 ?m are mixed with the binder, shaped into spheres having an average diameter between 0.3 and 7 mm, and subsequently calcined. Also disclosed is the use of the catalyst for converting methanol into olefins, in particular propylene. Also disclosed is a method for producing olefins from methanol, in which a feed gas is fed across the catalyst.Type: GrantFiled: November 16, 2010Date of Patent: December 6, 2016Assignees: CLARIANT PRODUKTE (DEUTSCHLAND) GMBH, AIR LIQUIDE GLOBAL E&C SOLUTIONS GERMANY GMBHInventors: Götz Burgfels, Manfred D.

Patent number: 9085500Abstract: A process for producing a product containing C3H6 and C2H4 includes simultaneous conversion of MeOH and EtOH in an adiabatic sequentially operated reactor containing a plurality of reaction stages. Each of the plurality of reaction stages of the reactor is provided with a fixed bed of a form-selective catalyst. A gaseous feed stream including MeOH, DME and H2O is charged to at least a first of the reaction stages of the reactor with a temperature in a range of 300 to 600° C. at a pressure in a range of 0.1 to 20 bar[a]. EtOH is fed into at least, one of the reaction stages of the reactor.Type: GrantFiled: November 25, 2009Date of Patent: July 21, 2015Assignee: AIR LIQUIDE GLOBAL E&C SOLUTIONS GERMANY GMBHInventors: Henning Buchold, Harald Koempel, Sven Pohl, Martin Rothaemel, Ulrich Wagner
