✦ Synopsis

Rates of gasification of a cellulose char have been determined in 0.1 atm of O,, H20, and CO,. Gasification was carried out in a reactor designed to provide precise control of reaction conditions and to reduce diffusion limitations of the reaction rate. Apparent activation energies were determined for each reaction to allow extrapolation of rates determined in different temperature ranges to a common temperature. The apparent activation energies for reaction in O,, H,O and CO, were found to be 28.0, 38.1 and 66.8 kcal/mole, respectively. The relative rates of reaction of the same gases at 800°C and a reactant gas pressure of 0.1 atm were found to be 1.6 x 104, 18 and 1.0, respectively.
