The present invention is a process for the production of methanol from a syngas feed containing carbon monoxide, carbon dioxide and hydrogen. Basically, the process is the combination of two liquid phase methanol reactors into a staging process, such that each reactor is operated to favor a particular reaction mechanism. In the first reactor, the operation is controlled to favor the hydrogenation of carbon monoxide, and in the second reactor, the operation is controlled so as to favor the hydrogenation of carbon dioxide. This staging process results in substantial increases in methanol yield.

Liquid phase methanol reactor staging process for the production of

The present invention is a process for increasing the capacity of a gas phase synthesis loop for the production of methanol from a syngas feed. The syngas feed is initially passed to a liquid phase methanol reactor to convert a portion of the syngas to methanol or methanol and higher aliphatic alcohols. The mixture is subsequently cooled to condense and recover the methanol and/or higher alcohols. The unreacted syngas is passed to a gas phase synthesis loop for further conversion and recovery of methanol.
