The evaluation of catalytic combustion of waste palm trunk derived biomass and biochar with perovskite supported by K2CO3 using the TG (thermogravimetric) under oxidation atmospheres was carried out. Catalyst activity system of K2CO3 supported on perovskite was studied. The effect of using developed catalyst and reference catalyst in the catalytic combustion of waste palm trunk derived biomass and biochar was investigated. Catalysts, biomass and biochar waste palm trunk samples separated into the size of 100μm to 250μm fractions were subjected to non-isothermal thermogravimetric experiments were performed with different atmospheres which consisted of nitrogen and oxygen with N2:O2 9:1 ratio, at heating rate of 2°C/min in the presence of 100cc/min total flow of N2 and O2. Alumina, K10Alumina and Ni10Alumina catalysts showed very poor catalytic combustion activity. However K10LMC82 or K2CO3/LaMn0.8Cu0.2O3 catalyst showed better catalytic combustion activity compared to the other catalysts, which indicated that perovskite oxide was more effective as a support for the combustion.
