In this study, pyrolysis characterization of peat and mushroom culture waste were investigated. The composite of the pyrolysis gas (volatile material) and char for each reaction temperature were investigated by using fixed bed reactor. As a result, in the case of peat, generation rate of volatile material was increased with increasing temperature and the ratios of monoxide and dioxide are higher than other components. Also, the ratio of hydrogen was increased with increasing reaction temperature. Biomass shows the similar behavior such as peat, however total generation amount was slightly more than peat. In the case of peat-char, C ratio was increased and H ratio was decrease with increasing the temperature. These result showed that dehydrogenation and carbonization had a relationship and progressed with increasing pyrolysis temperature. In the case of biomass, similar result was shown.
