The kinetics of gasification of carbon deposited on nickel foils and nickel-alumina catalysts by steam, carbon dioxide and hydrogen are reported for the temperature range 450-85O"C. At atmospheric pressure steam is the most effective gasifying agent. In all cases, the kinetic data obtained at lower

and carbon monoxide can be readily oxidised electrochemically at the three phase boundaries (Ni /YSZ/gas), generating electricity: In general, when hydrocarbons are exposed to high temperatures their dissociative adsorption on the surface of the nickel based catalyst results in carbon formation and
The deposition of carbon from CH\* and CO on Ni/SiOz catalysts was studied in pulse-flow experiments as well as volumetrically with a low-field magnetic permeameter. It was found that carbon, deposited from CH\* according to: CH, -+ C + 4H, gave rise to the formation of nickel carbide, N&C, only at
