The increasing environmental pollution and depletion of fossil fuels have led to a search for ecofriendly, renewable, and sustainable alternative energy sources. Biomass is a promising alternative energy carrier that can be utilized instead of conventional resources. Terminalia arjuna is a fast-growing tree belonging to family combretaceae. The purpose of this paper is to study the proximate, spectral, thermal, ultimate and gasification properties of selected woody material for power generation. The proximate analysis of Terminalia arjuna is amenable for biomass-based power generation due to their ideal energy value (4168 Kcal/kg). The FT-IR assignments exhibit high volatility due to the presence of carboxylic, amine, and hydroxyl groups. Ultimate analysis showed that the selected woody material has major hydrocarbon content (12.59% & 67.36%) which is suitable for energy production. TGA and DTG decomposition demonstrates that the selected woody material can be used as a feedstock for thermochemical conversion process to produce biofuels with high efficiency. In 5kW/h downdraft biomass gasifier produce clean gas with higher heating value ensure the gasifier efficiency and the bioenergy potential of the selected woody material as a feedstock for energy conversion. In a holistic perspective, the results showed that Terminalia arjuna exhibited superiority in all energy properties that advance support to its amenability for energy utility.
