The evolution characteristics of degradation gas from highly densified biomass briquette called Bio-coke (BIC) are experimentally and numerically investigated. In the present study, evolution rates of both volatile and water from the sample are determined as Arrhenius-type equations and the constants such as frequency factors and activation energies are given by the thermo-gravimetric analysis. It is confirmed that the model used in the study can qualitatively describe the gas evolution from the BIC sample. With high water content, the time volatile evolution start is delayed because much heat is consumed to evaporate the water. In the period before the volatile evolution start, the rate of evolved water to the whole water increases with increasing the water content of the BIC sample.
