Pyrolysis of biomass is one of the effective methods to give additional value to biomass. In this study, Japanese ceder (Cryptomeria japonica) and Moso bamboo (Phyllostachys heterocycle f. pubescens) were used as typical resources in Japan. Pyrolysis of the biomass was conducted with laboratory pyrolyser under various pyrolysis conditions to estimate the effects of pyrolysis temperature on the bio-oil composition. The results shown that the major pyrolysis products were Levoglucosan, Furans and Guaiacol derivatives. Those compounds were known as valuable products, and the yield of those products was higher at 480 ℃ pyrolysis. It is known that increasing the pyrolysis temperature accelerates the demethylation and demethoxylation. Thus, the production yield of the phenol and catechol were increased as raising temperature. Yield of flammable gas (H_2, CO, CH_4) was increased with increasing pyrolysis temperature, and char yield was decreased (39.3-22.6 wt%).
