Abstract

In this study, two different wood wastes were selected based on their availability at different locations in Tamil Nadu for the production of biochar and Prosopis julifera was used as combustion fuel. The properties of wood waste and combustion fuel was studied and selected wood wastes had higher volatile content (80%) for pyrolysis conversion and Prosopis julifera had a higher heating value of 20.13 MJ/kg, which enables good combustion to provide heat energy for the production of biochar. The biochar production was optimized with the different mass ratio of Prosopis julifera (0.25, 0.50, 0.75 and 1.0 kg). The optimization of biochar production was carried out in a semi-indirect non-electric pyrolytic reactor had a capacity of 1 kg. The maximum optimized yield of biochar obtained from casuarina wood (Casuarina spp) was 36% and 35% from sawdust of teak wood (Tectona grandis) with a mass of 0.75 kg combustion fuel. Characterization of biochar shows the presence of higher total organic carbon content (84-87 %).
