Batch reactor studies of methanol to gasoline over mixed oxide + H~+/ZSM-5 catalysts

摘要

Converting syngas to gasoline is an attractive proposition given the current price of oil and an ever increasing demand for gasoline. Syngas can be obtained from non-renewable resources by steam reforming of petroleum hydrocarbons or by coal gasification, or from renewable resources by gasification of biomass. Gasoline is an important fraction of petroleum, which is widely used as a transportation fuel. Syngas can be converted directly to gasoline range compounds by Fischer-Tropsch chemistry using Co or Fe catalysts. An alternative route to convert syngas to gasoline is to convert syngas to methanol over Cu/ZnO/Al2O3 catalyst and then convert the methanol to gasoline (MTG) over H~+/ZSM-5. In an effort to develop a composite catalyst to convert syngas directly to gasoline, we have studied the MTG reaction over various alcohol synthesis + H~+/ZSM-5 catalysts over a wide range of reaction conditions.
