Abstract
The aim of this experimental work to investigate the effect of Coal bottom ash (CBA) on thermal degradation of palm kernel shell (PKS). Thermal decomposition for 50 and 25 % CBA percentage in PKS samples were carried out it thermo gravimetric analyser (TGA) in non isothermal condition. The effect on the weight loss in the different region for 50 % and 25 % of CBA was investigated and found weight loss % increased by decreasing CBA percentage. It was observed the weight loss for 25 % CBA was 10.5 and 32.81 % at temperature region 0-260 and 250 -650 oC.Whereas, weight loss % was 8.8 and 27.6 % in the same temperature regions for 50% CBA. On the other hand the weight loss was small for 25 % CBA than %0 % CBA at 650 oC. Secondly the residual was left 60.5 and 54 % for 50% and 25 % of CBA. Moreover DTG profile shows that the hemicelluloses decomposed at temperature above 270 oC and Calloused at 370 to 400 oC. It was investigated most of the weight loss and DTG rate was observed in the temperature range of 300 to 400 oC. This fundamental study for optimization of CBA % our current work in gasification.
