A simple kinetic model based on carbon conversion in three consecutive stages was used to examine the kinetics of hydrogasification in four different types of reactors with hydrogen partial pressure and temperature ranging from 15 to 205 atm and 425 to 1200/sup 0/C, respectively. Depending on the type of reactor and temperature range, the activation energies varied from 4.4 to 53.9 kcal/mole of carbon hydrogasified. Severe mass transfer resistance was evident under some conditions. Correlations based on carbon conversion have been developed for calculating the char yield and the dispositions of coal hydrogen, nitrogen, sulfur, and oxygen, independent of reactor conditions and geometry.
