Abstract: A process for isobutanol synthesis is described. Ethanol and synthesis gas (syngas) are reacted in the presence of a heterogeneous catalyst in a first reaction zone. The products of the first reaction can be separated into one or more streams comprising methanol and propanol. The methanol and propanol from the first reaction are reacted in the presence of a second catalyst to form isobutanol in a second reaction zone.
