Experiments of the "semi-carbonization" pyrolysis were conducted for cellulose : the main component of woody biomass, citric acid and their mixtures in order to clarify the optimal pyrolysis condition and the effect of acid additives on the semi-carbonization. The acid additive promoted dehydration of woody biomass, and affected the weight yield of char within the temperature region of the semi carbonization. The analytical model to evaluate the energy value of the semi-carbonized fuel was presented based on the reduction in the value due to the transportation. The optimal pyrolysis condition of the semi-carbonized fuel was clarified for the dimensionless distance of the transportation. It was found that the acid additives contributed to saving the energy consumption of the "semi-carbonization" pyrolysis process and improving the transportation.
