Abstract
The invention provides methods and apparatus for selectively producing ethanol from syngas. As disclosed herein, syngas derived from cellulosic biomass (or other sources) can be catalytically converted into methanol, which in turn can be catalytically converted into acetic acid or acetates. Finally, the acetic acid or acetates can be reduced to ethanol according to several variations. In some embodiments, yields of ethanol from biomass can exceed 100 gallons per dry ton of biomass.
