Catalytic hydrogenation of carbon monoxide and dioxide over steel

Authors


Abstract

The hydrogenation of carbon monoxide and carbon dioxide on various steel catalysts was studied in the temperature range of 800° to 1,300°F. and at pressures from 5 to 30 atm. The feed gases (3.75 to 20 SCFH) were passed over a catalyst bed of 1/8-in. steel balls supported in a brass-lined reactor 0.81 in. in diam. The percentage of carbon oxides in the feed was 30% in the runs using a H2[BOND]CO2 feed and varied from 15 to 38% in the runs with a H2[BOND]CO feed. The effects of temperature, pressure, feed composition, space velocity, and mass velocity were studied. Carbon deposition did not affect the activity of the catalyst and could be removed readily.
