摘要

The escalating energy need caused by the global population expansion has compelled innumerable nations to alternate to sustainable and cleaner sources of energy for economic growth. Biomass as a sustainable energy source is often described through various metrics, predominantly by chemical composition, functional groups, calorific value, ash content, and other minor attributes. Moreover, these characteristics established from previous literature were found to be location-dependent. However, there is insufficient data to comprehensively evaluate commonly found biomasses of Indian origin and appraise their thermochemical potential. This study explores the energy and utility potentials of eight biomasses; poplar wood, eucalyptus wood, sugarcane bagasse, coconut shell, switchgrass, congress grass, rice husk, and corn cob through thermochemical characterization. Outcomes reveal that the feedstocks have high volatile matter (VM) of 74.3% ± 1.84% for eucalyptus, and 63.9% ± 0.5% for rice husk, the maximum high heating value (HHV) is 18.23 MJ/kg for poplar, and the minimum is 15.52 MJ/kg for congress plant. They also exhibit low moisture and ash content, which enhances combustion and prevents slagging. Attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FTIR)–based prominent peaks recorded are attributed to C-O, C-H, C = C, and O–H functional groups. Thermogravimetric analysis (TGA-DTG) demonstrated that maximum weight loss and major volatile gasses are released in the range of 220–411 °C ascribed to cellulose and hemicellulose, and decomposition of lignin happens at elevated temperatures. Pyrolysis–gas chromatography-mass spectrometry (Py-GCMS) shows several decomposition byproducts and pathways for the production of valuable industrial chemicals. Energy dispersive x-ray spectroscopy (EDX) and elemental mapping showed that the biomass mainly comprises carbon and oxygen.
