Woody biomass is a hopeful energy resource to reduce greenhouse gas emission, and it is widely used in North Europe. Although Japan has much forest, and emits large amount of greenhouse gas, little amount of woody biomass is utilized for energy production. One of the reasons is that most forests in Japan are located in steep mountain ranges. Therefore. we must reduce the labor and the costs for ingathering and transportation of the woody biomass energy to utilize it in Japan. The object of our research is to improve the calorific density of woody biomass pellets, and reduce the transportation cost per unit energy. We adopted the 'semi-carbonizing' method for the purpose. Woody biomass is generally used after desiccating because green woods include about 50% (mass fraction) of free water and it reduces the calorific value of the fuel. Woody biomass could be dehydrated more by decomposition of cellulose and hemi-cellulose during carbonization. The organic volatiles, however, are lost during the process, and the energy yield of the carbonized wood is reduced. Therefore, semi-carbonizing condition, on which maximum energy yield can be achieved, should exist. We examined the optimum semi-carbonizing condition for pelletizing in the present study.
