✦ Synopsis

The effects of various metals on gasification rate and the composition of the evolved gas during the steam gasification of carbons have been examined in detail. Three metal salts (K,CO,, Na,CO,, CaCO,) and two metal oxides (Fe,O,, Ni,O,) were supported on two kinds of carbonaceous material (coconut shell carbon and carbon black). Samples were gasified in a steam atmosphere at temperatures between 600 and 83572, and the changes in the sample weight and the gases evolved were measured in detail. The metals Na, K and Ni greatly increased the gasification rates. The rate equations were found to be dependent on the nature of the metal, and were divided into three groups. The ratio of CO to CO, in the gas produced was also greatly affected by the nature of the metal.
