Abstract

Abstract: This research is intended to study fuel property and thermal decomposition behavior of hydrothermally treated municipal solid waste (HTT-MSW) during combustion. In the experiment, simulated MSW was used as a raw material (Raw-MSW) to produce solid biofuels at the hydrothermal reaction temperature of 180, 200, and 220 ºC for 30 min by a lab-scale autoclave. The results showed that the higher reaction temperature in the experiment increased the heating value of the product. Before the HTT process, the Raw-MSW has 20 MJ/kg of heating value, after processed, the energy density was increased to 21.8, 26.4, 31.4 MJ/kg for 180 to 220 ºC respectively. From thermogravimetric analysis result (TGA), mass loss profile of Raw-MSW and HTT-MSW showed two major decomposition peaks and the effect of HTT on combustion was that the decomposition profile became smoother. From kinetics study on non-isothermal thermogravimetric data, the activation energy (E) of HTT-MSW was higher than that of the Raw-MSW and the E values were around 35 to 80 kJ/mol for the Raw-MSW and HTT-MSW.
