Effect of Process Temperature on Coconut Shell Biochar Production and its Iodine and Methylene Blue Adsorption

摘要

Biomass derived biochar materials are in greater need as an effective adsorbent in variety of applications. Coconut shell biochar was produced from slow pyrolysis process at different temperatures (400, 500, 600, 700 and 800°C) and was characterizedfor proximate and elemental composition. Biochar with fixed carbon and elemental carbon of 86.38 and 82.14%, respectively was produced achieved at 800°C. Coconut shell biochar was examined for its adsorption capacity using iodine and methylene blue (MB)adsorption. Maximum iodine adsorption of 550 mg g^and MB adsorption of 65.6 mg g1 were observed for biochar produced achieved at 700°C and 800°C, respectively. Results concluded that biochar produced at 700°C had more microporous and biochar producedat 800°C had more mesoporous with higher iodine and methylene blue adsorption.
