This article investigates possible catalysis mechanisms and the effects of mineral impurities using a typical char and a pure graphite powder. Chemical reactions in the presence and absence of added alkali catalysts are compared. Catalytic effects of alkali carbonates and other salts in the gasification of coal char and graphite in steam and CO/sub 2/ were studied. Patterns of catalytic activity for the various additives are similar for both char and graphite. Mechanisms for the alkali carbonate catalysis that rely on metal atom formation are thermodynamically feasible. The reactivity of char is influenced by such factors as charring temperature, porosity, and the presence of mineral impurities.
