Methanol is converted in a plurality of conversion zones at temperatures selected from within the range of 500 DEG to 1200 DEG F. and reactant residence time within the range of 0.5 to 60 seconds in the presence of crystalline zeolite containing catalyst to particularly form products of desired volatility and octane in the gasoline boiling range. The distribution of methyl groups on C6+ aromatics formed in the process to desired products is particularly accomplished under selected temperature and reactant contact time conditions. |
