Fundamental studies of catalytic gasification
Previous work has shown that chars and coal can be gasified with steam in the presence of alkali-transition metal oxide catalysts or alkali-earth alkali catalysts at relatively low temperatures. These studies are to be extended to the investigation of the amounts of catalysts required and whether a throw away catalyst can be used. Fresh versus stored char will be gasified to determine the role of oxidation of the char on gasification rates. Less expensive catalyst materials such as sodium instead of potassium and iron instead of nickel will be explored. Reaction rates will be determined in the presence of nitrogen, Co and CO{sub 2}. Reactions of methane and carbon solids in the presence of an oxidizing agent such as water, oxygen, and/or carbon dioxide will be explored in the presence of similar catalyst. This quarter, additional experiments on catalytic gasification of coal were carried out. Major emphasis, however, was on the production of C{sub 2} and higher hydrocarbons from methane at very high selectivities. Catalysts studied include KCaNiO. 6 figs., 1 tab.
