Abstract

In this research, Bauhinia monandra seed and pod were investigated for the first time as a source for bioenergy production. Proximate analysis revealed that the biomass seed contains high volatile matter of 88.96 % and pod 92.64 %, the low ash content of 3.16 % for the seed and 0.89 % for the pod, with fixed carbon of 1.87 % for seed and 0.71 % for the pod. The ultimate analysis showed carbon, sulfur, and hydrogen are 41.45 %, 1.79 % and 6.28 % for the seed, while the pod had 42.25 %, 1.77 %, and 6.21 % respectively. Higher Heating Value ranges from 14.26 – 14.69 MJ/kg were obtained for the biomass using three mathematical formulas. The Pyrolysis behavior of the biomass revealed four degradation peaks attributed to the removal of water molecules and the degradation of hemicellulose, cellulose, and lignin respectively. The kinetic parameters (activation energy (Ea) and frequency factor (A) determined from TG/DTG data revealed a relatively high Ea (35.5 – 41.56 KJ/mol). The structural composition of the seed indicated 43.50 %, cellulose, 20.00 % hemicellulose, 19.50 % lignin, and 16.00 % extractive material, and pod had 37.50 % cellulose, 33.50 %
