The catalytic hydrogasification of coal is successfully carried out by Tomita and Huettinger and their co-workers using nickel and iron as catalysts. On the other hand, hydrogasification of coal char and carbon has attracted a little attention because of strong thermochemical suppression at higher temperature and low gasification rate compared with the gasification by H/sub 2/O or CO/sub 2/ and also because only noble metals such as platinum show high catalytic activity. But, it is known that iron group metals iron, cobalt and nickel also have catalytic activity for hydrogasification of carbonaceous materials like graphite. The activity and reaction mechanism are well studied using controlled atmosphere electron microscopy. This study shows the reactivity of iron, cobalt and nickel catalyzed char gasification with hydrogen at atmospheric pressure, and that the mixing of supported nickel catalyst with metal loaded char remarkably increases hydrogasification rate.
