A catalytic process is provided for converting a C1-C4 monohydric alcohol, an ether derived from said alcohol or a mixture of such alcohol and ether to a hydrocarbon mixture rich in C2-C3 olefins and mononuclear aromatics with high selectivity for para-xylene production by contact, 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. |
