Due to critical
environmental issues, increasing future energy supplies and decreasing reserved
energy resources are currently the subject of comprehensive research. The use
of biomass as a renewable energy resource may be helpful in solving current
energy shortfalls, particularly for countries that have abundant biomass
resources. In this study, pyrolysis of coal, Acacia Mangium wood, and their respective blend samples were
investigated using proximate analysis and Thermogravimetric (TG?DTG). A mixture
of coal and A. Mangium wood with a
weight ratio 100:0, 90:10, 50:50, 10:90, and 0:100, were used and
non-isothermal conditions at a constant heating rate of 5, 15, and 30°C/min
were applied. Thermal evolution profile analysis of the pyrolysis process
confirms that the reactivity of the fuel increased with the increasing
proportion of the biomass in the fuel. The reactivity and maximum temperatures
increased with the increasing heating rates. Proximate analysis showed the
potential of biomass of A. Mangium
wood to be used as a mixture with coal in terms of low ash and high volatile
matter content.
