  • Selective process for conversion of syngas to ethanol
    Patent number: 8288594
    Abstract: The present invention provides processes for selectively producing ethanol from syngas. In some variations, the process comprises converting biomass-derived syngas to dimethyl ether, carbonylating the dimethyl ether to methyl acetate, hydrogenating the methyl acetate to methanol and ethanol, and recovering the ethanol product. The methanol is preferably recycled by converting to hydrogen and carbon monoxide for introduction back into the process at distinct points. In certain variations of this invention, fresh syngas feed is introduced downstream of the first unit operation in the sequence. High yields of ethanol from biomass can be achieved according to the disclosed processes.
