Synthesis of high caloric fuels and chemicals via ketene and diketene intermediates

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.

主权项

1. A method for the preparation of a mixture of alkyl compounds, the method comprising:
a) preparing a ketene of the formula I: b) reacting the ketene in a self-addition reaction to form a diketene of the formula II; and wherein: each R1 is independently H or C1-6 alkyl; and each R2 is independently H or C1-6 alkyl; c) hydrogenating the diketene of the formula II in the presence of a metal catalyst to form the mixture of alkyl compounds comprising 1-butanol, 2-butanol, 2-pentanol, 1-hexanol, 2-hexanol, 2-heptanol, 4-heptanol, 3-methyl cyclohexanol, and 2,6-dimethyl-4-heptanol.
