To investigate applicability of diverse coal type to hydrogasification process, hydrogasification were performed with two kinds of Chinese coals, Urumqi and Datong coals and the results were compared with that of Taiheiyo coal. It was found that total gaseous product yields (gas yield) as well as the amounts of major products such as methane, ethane, CO and BTX decreased in the order of Taiheiyo, Urumqi, and Datong, which was in agreement with the sequence of VM contents for the three coals. Comparing the relationships of carbon conversions to individual products with gas yield shows that coal type has little influence on hydrogasification mechanism.
