ABSTRACT:
A process for the continuous production of methanol through contacting at least one feed stream containing at least carbon monoxide and hydrogen, and optionally carbon dioxide, with a simulated moving bed acting as a catalyst for methanol synthesis and an adsorbent for the methanol formed has been developed. The carbon monoxide and hydrogen are catalytically reacted to form methanol which is separated from the carbon monoxide and hydrogen by concurrent adsorption. The methanol is desorbed using a carbon dioxide or hydrogen desorbent and collected. A specific embodiment is one where the feed stream is introduced to the simulated moving bed at a temperature from about 210.degree. to about 270.degree. C. and the desorbent is introduced to the simulated moving bed at a temperature of about 150.degree. to about 250.degree. C.
