Physico-chemical and combustion analyses of bio-briquettes from biochar produced from pyrolysis of groundnut shell

The initiative of using biomass as a preference source energy is vindicated by its availability, abundance, easy accessibility and eco-friendly nature. This therefore calls for the conversion agricultural wastes to usable form. study aimed investigate physicochemical combustion properties briquettes obtained from pyrolyzed biochar groundnut shell. shell briquette bonded with cassava starch binder were molded analyzed. Proximate analysis, ultimate analyses, Scanning electron microscopy (SEM), Calorific values, density compressive strength, among other properties, determined fabricated briquettes. A high heating value 45.20 MJ/Kg was recorded compared 25.20 raw briquette. While ash contents 5.12 % 6.40 respectively. It took approximately 10 minutes boil 1000 cm3 water, while boiled same quantity water in 20 minutes. finding this shows that pyrolysis suitable fuel production.
