专利号:US-9080119-B2 优先权日:2011-11-10 标 题:Synthesis of high caloric fuels and chemicals including pentanol from coal, natural gas, and biomass 发明人:HENRI JOHN; ZYGMUNT JAN; BERGGREN MARK; ZUBRIN ROBERT 权利人:PIONEER ENERGY INC; Pioneer Energy 摘要: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. Ketene and ketonization chemistry along with hydrogenation reactions are used to synthesize fuels and chemicals. In another embodiment, ketene used to form fuels and chemicals may be manufactured from acetic acid which in turn can be synthesized from synthesis gas which is produced from coal, biomass, natural gas, etc.
