Carbonization process with pig manure is carried out to estimate the reaction kinetics with increasing carbonizationtime and temperature in the process. From the examination of conversion characteristics of pig manure, carbonizationreaction can be described by the 1st order kinetic reaction. Degree of carbonization, which can be expressed by C/H moleratio, is increased with increasing carbonization temperature. As increased carbonization temperature from 250oC to 400oC,reaction rate constant in the 1st order kinetic reaction is also increased from 0.0622min−1 to 0.1999min−1. Frequency factorand activation energy in Arrhenius equation for pig manure in the carbonization process can be decided by 1.06×10−3min−1 and 5441.8kcal/kmole, respectively. From the results of the reaction kinetics including TGA and SEM analysis,it is desirable that pig manure should be carbonized below carbonization temperature 400oC.
