Methods and apparatus for synthesis of alcohols from syngas

摘要

This invention provides a method for producing ethanol and 2-propanol from syngas, the method comprising: (a) converting syngas into methanol using a methanol-synthesis catalyst; (b) converting methanol into ethylene and propylene using a methanol-to-olefins catalyst; and (c) hydrating ethylene into ethanol and propylene into 2-propanol. As taught herein, the combined yield of the ethanol and the 2-propanol from biomass can be at least 100 gallons per dry ton biomass. In certain embodiments, the yield of ethanol is at least 100 gallons per dry ton biomass. In some embodiments, the yield of 2-propanol is at least 50 gallons per dry ton biomass.

1. A method for producing ethanol from syngas, said method comprising:
(a) converting syngas into methanol in the presence of a methanol-synthesis catalyst; (b) converting at least some of said methanol from step (a) into a composition including ethylene and propylene in the presence of a methanol-to-olefins catalyst; and (c) hydrating at least some of said ethylene into ethanol.
