CATALYST FOR PRODUCTION OF LIQUID HYDROCARBONS FROM DIMETHYL ETHER Russian patent published in 2008 - IPC B01J29/46 B01J29/48 B01J23/06 B01J21/04 C07C1/20 

FIELD: industrial organic synthesis and catalysts.

SUBSTANCE: liquid hydrocarbons that can be used not only as motor fuel components and additives in production of high-octane gasolines with content of aromatic hydrocarbons no more than 20 wt % but also as target products of organic synthesis are obtained catalytically in the form of mixture from dimethyl ether. Catalyst for this process based on zeolites and including zinc and/or cobalt oxides and alumina as binder is characterized by that zeolite utilized is CVM zeolite and/or clinoptilolite and further contains chromium and boron oxides, whereas proportions of catalyst constituents are the following, wt %: chromium oxide Cr₂O₃ 2.0-4.0, cobalt and/or zinc oxide (CoO and/or ZnO) 2.0-4.0, boron oxide B₂O₃ 3.0-5.0, CVM zeolite and/or clinoptilolite 10-30, and alumina - the rest.

EFFECT: increased yield of motor fuel components at content of aromatic hydrocarbons not exceeding 20%, and increased stability of catalyst.
