Abstract
Abstract A catalytic process is provided for converting a feed containing a C1-C4 monohydric alcohol by contact of said alcohol, under conversion conditions, with a catalyst comprising a crystalline aluminosilicate zeolite having a crystal size of at least about 1 micron, a silica to alumina ratio of at least about 12 and a constraint index, as hereinafter defined, within the approximate range of 1 to 12. The zeolite contains a Group 2B and a Group 8 metal or metal compound plus magnesium, either per se or in compound form.
