Abstract
The present invention relates to a process for improving reactor volumetric productivity in the production of methanol wherein a synthesis feed gas stream containing hydrogen and carbon oxides is contacted with a catalyst slurry containing greater than about 25 wt % of a powdered copper-containing catalyst having a porosity of from about 30% to 70%. Volumetric productivity is maximized in the process by controlling a single parameter, gas holdup, wherein holdup is maintained within the range of about 14% to 26%.
