Catalytic Combustion of Waste Palm Trunk Derived Biochar and Biomass

Abstract:

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/LaMn_0.8Cu_0.2O₃ 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.
