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

Using an isothermal flow reactor of annular configuration, the rates of carbon deposition from CH4 and C,O, have been measured over the respective temperature ranges, 1168ยฐ-13720K and 900"-1025ยฐK. Under the experimental conditions employed, deposition from both of these compounds is found to be cont
new method for forming isotropic, laminar, and columnar pyrolytic carbons is proposed. For this, a low RPM (below 2.4rpm) tumbling bed has been used to deposit pyrolytic carbons from hydrocarbon gases. All deposits were made on graphite substrates from propane and methane at a constant temperature o
York). A simple model of the deposition of pyrolytic carbon is proposed to explain the apparent inconsistencies between properties and structure. This model considers the importance of the nucleation rate, diffusion, and surface reactions and is based on structure determinations by density and stres
## When surface carbons are produced by the pyrolysis of gaseous hydrocarbons in a silica tube heated to about lOOO"C, spectrographic analysis shows the presence of up to 1% silicon even when the carbon is deposited on a metal substrate. It seems likely that hydrocarbon radicals react with silica
