SYNTHESIS OF ETHANOL AND HIGHER ALCOHOLS BY HYDROGENATION OF KETENE

摘要

Ketene chemistry and hydrogenation reactions are used to synthesize fuels and chemicals. Ketene from acetic acid is hydrogenated to form fuels and chemicals; acetic acid can be synthesized from synthesis gas which is produced from coal, biomass, natural gas, etc. In one embodiment, the present application discloses methods to selectively synthesize higher alcohols and hydrocarbons useful as fuels and industrial chemicals from syngas and biomass.
