Abstract
This paper describes product distribution from hydrogenation of model materials as heavy liquid elements by pyrolysis of wood wastes mixture containing adhesive, plastics, and so on. The mixing effects of materials on reaction were also discussed. As a result, product distribution was differed by hydrogen pressure. It was shown C_6H_6 and C_2H_6 influenced as middle products which could be converted to CH_4. Whole reaction was enhanced by pressure increase. The effects of mixing on increasing in CH_4 yield were observed even it was small. It is not shown the possiblity exothermic reaction promotes endothermic reaction in this mixing system.
