Patent ·
OSTI ID:5451269

This patent describes in a method for producing a hydrocarbon mixture by catalytic conversion of an alcohol feed over a crystalline aluminosilicate zeolite catalyst, the improvement, whereby the proportion of olefins in the hydrocarbon mixture is increased. It comprises contacting the alcohol feed under sufficient alcohol conversion conditions including a reaction temperature of from 350{sup 0} to 600{sup 0}, a WHSV of alcohol of 0.5 to 10, and a reaction pressure of form 1 to 100 atmospheres, with a crystalline aluminosilicate zeolite characterized by having a constraint index within the approximate range of 1 to 12 and a silica to alumina ratio of from 298 to 2000.
