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%.

In a process for the production of alkanols as a product, co-product or intermediate in a liquid phase reactor wherein a feed gas containing hydrogen and carbon oxides is reacted in the presence of a catalyst slurry comprising a solid phase catalyst suspended in a liquid solvent under sufficient temperature and pressure to effect reaction between said hydrogen and carbon oxides to form said alkanol and then removing said alkanol, the improvement for maximizing reactor volumetric productivity which comprises: (a) utilizing a catalyst slurry having greater than about 25 wt % of a powdered copper-containing catalyst having a porosity of between 30% and 70%; and (b) passing said feed gas into said slurry at a rate such that gas holdup is maintained between about 14% to 26%
