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. Waste plastics mixed with coal were seems to be suitable materials as a means of feedstock. Hydrogasification of polyethylene singly and a mixture of coal/polyethylene were carried out. Synergistic effect was observed when polyethylene was mixed with coal as raw materials, increasing in yield of methane. From the change in the temperature monitored inside the reactor, heat of exothermic hydrogenation of polyethylene may supplement the heat of endothermic pyrolysis of coal to enhance the overall reaction. In this study, helium was used as reaction atmosphere instead of hydrogen to clarify the mixing effect. As a result, in the case of pyrolysis, less synergistic effect than hydrogasification was observed.
