专利号:US-2014245658-A1 优先权日:2013-02-08 标 题 :Synthesis of ethanol and higher alcohols by hydrogenation of ketene 发明人:HENRI JOHN T; ZYGMUNT JAN; BERGGREN MARK; ZUBRIN ROBERT 权利人:PIONEER ENERGY INC 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.
专利号:US-4790985-A 优先权日:1986-10-16 标 题 :Synthesis of sodium aluminum hydride 发明人:NELSON GUNNER E 权利人:ETHYL CORP 摘要:In the direct synthesis process for producing NaAlH4 (pressure hydrogenation of Na and Al in a liquid phase reaction medium at an elevated temperature) advantages are realized by insuring that the initial reaction mixture contains a small amount of water and/or an alcohol. In particular, the induction period is shortened. And, the time, trouble and expense of purifying and pre-drying the reaction medium are avoided.
