The technical features and problems of hydrogasification process.
Mamoru Kaiho · Journal of the Fuel Society of Japan · 1990
In order to appreciate the hydrogasification process, its cold gas efficiency was compaired with that of methanation process. It was concluded that the efficiency of hydrogasification was better than that of methanation because the oxygen ratio employed in former process was lower than that of latter one.The heat of reactions between carbon and hydrogen to form methane and BTX were examined theoretically. It was considered that the heat would be insufficient to keep the temperature of practical reactor in adequate level when coal was gasified with excess hydrogen. Some methods to supply heat to gasifier were proposed and their technical problems were discussed.
