PRODUCTION OF C 5 + AROMATIC-RICH GASOLINE FROM C 1 TO C 4 ALIPHATIC OXYGENATED HYDROCARBON FEEDSTOCK AT VARIABLE INLET TEMPERATURE

摘要

A catalytic conversion process for reacting lower aliphatic C1-C4 oxygenates, such as methanol, to produce gasoline boiling range hydrocarbons. Improved cycle average gasoline yield is sustained without a substantial reduction in cycle average gasoline octane number by selectively programming the conversion reactor inlet temperature during a process cycle.
