Abstract
The hydrogenolysis of Sumiyoshi coal was studied at 400°C under the reaction pressure of 110 to 220 atm. The reaction rate constant was calculated from the rate of decrease of unreacted coal. The data obtained were expressed as a first order reaction consisting of two steps. The rate constant in the second step increased linearly with the hydrogen pressure. But the rate constant of the direct production of oil from coal in the first step was almost constant.Keywords
