Steam gasification of two Hyper-coals with the physical addition of about 6% K_2CO_3 was conducted at 1023K on a thermogravimetric apparatus equipped with an on-line quadruple mass spectrometer. The catalytic gasification of the Hyper-coals demonstrated much higher gasification rate than the catalytic gasification of the raw coals. Interaction of K_2CO_3 with mineral matter in raw coal formed water-insoluble potassium compounds such as potassium aluminosilicates and thus reduced the catalytic activity, while no such negative reactions occurred for the Hyper-coals. The steam gasification of the Hyper-coals with K_2CO_3 was also found to be favorable for the high-yield production of hydrogen.
