This invention covers a process for converting a feed comprising at least one lower aliphatic alcohol having from 1 to 3 carbon atoms or a corresponding ether of such an alcohol to hydrocarbon products comprising linear olefins. The process comprises contacting the feed in a reaction zone with a catalyst comprising material having a large crystal ferrierite aluminosilicate structure. An effluent is withdrawn from the reaction zone, which comprises linear olefins. Linear olefins may then be separated from the effluent. The aliphatic alcohol having from 1 to 3 carbons is generally methanol and the preferred ether is dimethyl ether. ZSM-35 is the preferred large crystal ferrierite structure of this invention.
A process for converting a feed comprising at least one lower aliphatic alcohol having from 1 to 3 carbon atoms or a corresponding ether of such an alcohol to hydrocarbon products comprising linear olefins, the process comprising contacting the feed in a reaction zone with a catalyst comprising material having a large crystal ferrierite aluminosilicate structure, the aluminosilicate catalyst comprising a hydrogenation component, the hydrogenation component comprising combinations of Group VIA and VIIIA metals, wherein the average crystal size is larger than 0.5 microns and is selected from the group consisting of ZSM-35,FU-9,ISI-6,NU-23and SR-D, withdrawing from the reaction zone an effluent comprising linear olefins, and separating the linear olefins from the effluent.
