Pyrolysis of coconut husk biomass: Analysis of its biochar properties

The effect of pyrolysis at different temperatures on the biochar characteristics of coconut husk was studied. The biochar obtained was then characterized by proximate and ultimate analyses, gross calorific value, pH, surface area, percentage yield, FTIR, and FE-SEM. The results show that there was a significant change in the volatile matter, carbon percentage, surface area, pH, and its functional group as temperature increases. The moisture content and percentage yield decrease with increasing temperature. Thus, the results show that the carbonization has a significant influence on the processing characteristics of coconut husk biochar.
