The effects of Fe + Ca and Ni + Ca dual catalysts on hydrogasification of coal char were studied between 1 and 30 atm and between 750 and 900{degrees}C. Promotions of Fe- and Ni-catalyzed reactions by added Ca were observed in the reactions of all coal chars used. The degree of promotion increased with increases in the amount of added Ca, temperature, and pressure. The initial surface area of coal char was found to greatly affect the activities of dual catalysts, probably due to different dispersions of catalyst particles at the stage of impregnation. The rate of Ni-catalyzed gasification increased with time during the isothermal mode, and the added Ca accelerated the rate increase. The results are discussed in comparison with the authors previous study using model carbons.
