Gasification rates of different carbonaceous materials were measured at temperatures from 1073 K to 1273 K and carbon dioxide partial pressure of 50 kPa. The surface areas of the chars were also measured at various levels of conversion. The conversion rates per unit BET surface area remained mostly constant over the range of higher conversion (X > 0.4) and rates thus evaluated were expressed by a common straight line in an Arrhenius plot. Thus under the experimental conditions used differences in the gasification rates of various carbonaceous materials were interpreted by use of surface area only.
