Abstract
The kinetics of carbon deposition are reported for the temperature range 773-1023 K. A reaction model composed of adsorption and reaction steps is proposed and compared with experimental data. In this model the rate equation of carbon deposition takes into account the catalytic action of nickel. The calculated results are in good agreement with the experimental ones. The activation energy and the heat of adsorption of CO are 59.3kJ/mol and 61.7kJ/mol, respectively.
