Abstract
Pyrolysis of woody biomass attracts attention as one of the methods of using biomass energy effectively. The phenomenon governing the pyrolysis are both heat transfer and chemical reactions. Although about 30% of moisture other than organic ingredients, such as cellulose and lignin, is included in the woody biomass, change of heat and mass transfer by moisture evaporation is hardly considered. In order to investigate about the influence moisture content of the biomass affects pyrolysis process, experiments (temperature and gas flow rate measurement, gas analysis) were conducted by dry and wet biomass.
