Abstract
Since the heating values of swine manures were very low at 859~1,075 kcal/kg, it was necessary to convert to carbonization residue by carbonization processes among thermal processes. The most important factor in the carbonization process of swine manure is the carbonization temperature, and it was evaluated the optimal range of carbonization temperature for swine manure in this study by the thermal characteristics and the reaction kinetics. The carbonization of swine manure could be described by the 1st order reaction and Arrhenius equation. The frequency factor (lnA) and the activation energy were estimated to be 3.05~13.08 and 6.94~18.05 kcal/mol, respectively. The range of optimal carbonization temperature range of swine manure was $260{\sim}300^{\circ}C$.
