Abstract
In order to make a quantitative investigation on the hydrogenolysis reactivity of high rank coal. The kinetics of the catalytic hydrogenolysis of Australian coal and two Japanese coals has been studied using a batch autoclave. The reaction rates were measured at 400°C and 450°C under high pressure of hydrogen.
The rate constants decreased with the increase in the rank of coal. Although the hydrogenolysis of Japanese coal consisted of two steps, the high rank Australian coal proceeded as one step.It was considered that this phenomenon was due to the relatively homogeneous structure of the high rank coal.
