Assessment of the combustion properties and energy potential of <i>Ricinodendron heudelotii</i> (Pax Heckel) husks

The use of biomass, such as seed husks, for fuel production through pyrolysis is a key technology aimed at replacing fossil fuels with renewable energy sources, thereby contributing to a cleaner environment. This study assesses the energy potential and chemical composition of the husks of Ricinodendron heudelotii , highlighting their suitability for biofuel production. The proximate analysis of the kernel husks revealed ash, volatile matter, fixed carbon, and moisture contents of 18.80%, 59.80%, 21.40%, and 8.60%, respectively. The elemental analysis showed carbon, hydrogen, and nitrogen ratios of 47.0%, 4.52%, and 0.54%, respectively. Additionally, the lower heating value was determined to be 18.29 MJ/kg for the husks (dry basis). This composition, comparable to that of other energy crops cultivated globally for energy production, suggests that R. heudelotii could compete with standardized species used as raw materials for biofuels. This study opens up new possibilities for using Ricinodendron heudelotii husks as significant woody biomass fuel for domestic or industrial heating.
