A novel process for methanol synthesis (Technical Report

Jan 01, · A benchscale reactor is being used to conduct studies of the conversion of synthesis gas to methanol by a novel process. In previous reports, we provided evidence for a two step reaction in series, the carbonylation reaction mainly taking place in a nonequilibrium region in the vicinity of the Cuchromite surface, and the hydrogenolysis reaction taking place on the surface of the Cuchromite.
