✦ Synopsis

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 temperatures (below WC) is consistent with control of the process by the chemical reaction. As the temperature increases, the rates of gasification by steam and carbon dioxide are limited by mass transfer effects. The concentration of methane near reaction sites affects the rate of hydrogen gasification above 650Β°C.

The effect of surface irregularities, grain boundaries and crystal orientation have been studied for the formation of carbon on nickel from acetylene at low pressures and at temperatures between 450 and 600Β°C. Carbon formation is greatly enhanced if the surface is rough and if there are gram boundar
