The present invention discloses and teaches new methods of converting
syngas into ethanol and/or other higher alcohols. Preferred embodiments
recycle methanol, partially convert it to syngas, and then convert this
additional syngas also to C.sub.2+ alcohols. Generally, the invention
provides reactors comprising catalysts capable of converting syngas to
alcohols with low selectivities to carbon dioxide and methane, and
further provides process strategies to separate and recycle unreacted
syngas as well as methanol produced by the catalyst. The invention is
capable of turning modest per-pass reaction selectivities to a particular
alcohol, such as ethanol, into economically significant net selectivities
and yields.
