Conversion of 2,3-butanediol to 2-butanol, olefins and fuels |
摘要 |
Embodiments of an integrated method for step-wise conversion of 2,3-butanediol to 2-butanol, and optionally to hydrocarbons, are disclosed. The method includes providing an acidic catalyst, exposing a composition comprising aqueous 2,3-butanediol to the acidic catalyst to produce an intermediate composition comprising methyl ethyl ketone, providing a hydrogenation catalyst that is spatially separated from the acidic catalyst, and subsequently exposing the intermediate composition to the hydrogenation catalyst to produce a composition comprising 2-butanol. The method may further include subsequently exposing the composition comprising 2-butanol to a deoxygenation catalyst, and deoxygenating the 2-butanol to form hydrocarbons. In some embodiments, the hydrocarbons comprise olefins, such as butenes, and the method may further include subsequently exposing the hydrocarbons to a hydrogenation catalyst to form saturated hydrocarbons. |

1. A method, comprising:
converting 2,3-butanediol to 2-butanol by
exposing a composition comprising aqueous 2,3-butanediol to an acidic catalyst to produce an intermediate composition comprising methyl ethyl ketone, andsubsequently exposing the intermediate composition to a hydrogenation catalyst to produce a composition comprising 2-butanol, wherein the hydrogenation catalyst is spatially separated from the acidic catalyst. |
