A Process for Improving the Ratio of Carbon Monoxide to Hydrogen in Water Gas

Carbon monoxide is a fundamental chemical material for many carboxide products. In the industrial process manufacturing carbon monoxide from water gas, if hydrogen can't be fully utilized, the production cost will be increased. In this paper, a process that the ratio of carbon monoxide to hydrogen can be improved by substitution of carbon dioxide for part of steam in water gas production by regenerative method is proposed. The results of chemical balance calculation show that after the introduction of carbon dioxide into the system, both carbon monoxide concentration and the ratio of carbon monoxide to hydrogen in water gas is significantly increased. The influence of the variation of process conditions is also discussed.
