Methanol-to-Gasoline, An Alternative Route to High Quality Gasoline

Methanol produced from coal or natural gas can be converted over ZSM-5 class zeolite catalyst to high quality gasoline. Process reactions and yields are shown to be viable, thus providing a unique way to manufacture liquid transportation fuels from solid or gaseous energy sources. The hydrocarbon composition and physical properties of the gasoline are very similar to those of conventional petroleum-derived gasolines. No engine or vehicle modifications are required to use it. Laboratory and vehicle tests show the performance characteristics of the finished gasoline to compare very favorably in all aspects with commercial premium gasolines.
