A char derived from Illinois No. 6 coal was gasified after impregnation with KOH-NiO. The gasification with steam resulted in almost identical results with those obtained from graphite. Gaseous products were hydrogen and CO/sub 2/ in a ratio of about 2:1. The char gave larger, but still small amounts of methane (about 1% of gas products) than graphite at gasification temperatures of up to 900/sup 0/K. Addition of CO to the steam feed to KOH-NiO impregnated graphite resulted in a 25% increase in the rate of gasification. While the gaseous products were hydrogen and CO/sub 2/ in a ratio of 2:1 as observed in previous experiments without added CO, the new data show that formation of H/sub 2/ and CO/sub 2/ in a 2:1 ratio is not due to a water gas shift reaction. Addition of hydrogen to the steam feed caused about a 25% decrease in the rate of gas production as did the addition of CO/sub 2/ instead of hydrogen. 1 ref., 5 figs.
