Self-purging pyrolysis of sugarcane bagasse biomass to Disor-Deredmicroporous Biochar production
Inthis study, biochar was produced from sugarcane bagasse in a modified muffle furnace without using a purging gas at different tem-peratures; 400 ̊C to 700 ̊C with increments of 50 ̊C at 25 ̊C/min heating rate. Biochar yields were significantly influenced by the de-volatization of biomass during t...

| Summary: | Inthis study, biochar was produced from sugarcane bagasse in a modified muffle furnace without using a purging gas at different tem-peratures; 400 ̊C to 700 ̊C with increments of 50 ̊C at 25 ̊C/min heating rate. Biochar yields were significantly influenced by the de-volatization of biomass during the pyrolysis and were inversely proportional to the temperature. The holding time was also found to have a significant effect on biochar yields. The maximum biochar yields from sugarcane bagasse, at 10, 20 and 30 minutes holding times, were 27.11, 26.35, and 28.48%, respectively. The highest biochar yield at different holding times was obtained at a temperature of 400°C. The physicochemical properties of biomass and biochar were analysed. The results obtained from characterization showed that SCBC30 showed the highest BET surface area of 348.12 m2/g. From the FTIR results, SCBC10 showed fewer peaks, which indicated a smaller presence of functional groups than SCB-BC20 and SCB-BC30 due to an incomplete transformation of raw SCB wastes to biochar |
