Hydrogasification is a process to produce methane which substitutes natural gas from coal. It has been considered to diversify feedstock of hydrogasification other than coal. Hydrogasification of polyethylene singly and a mixture of the coal and polyethylene (50:50) were carried out. Synergistic effect was observed when polyethylene was mixed with coal for raw materials, increasing in yield of methane. From the change in the temperature monitored inside the reactor, heat of reaction seemed to be dominant for the synergistic effect. Heat of exothermic hydrogenation of polyethylene may supplement the heat of endothermic pyrolysis of coal to enhance the overall reaction. In this study, the ratio of polyethylene and coal mixture was varied to clarify the mixing effect. The amounts of products were analyzed and reaction enhancement affected by mixing was discussed from the methane yield. As a result, synergistic effect was observed when the ratio of polyethylene and coal mixture was varied.
