Abstract
Due to the growing energy demand and damaging consequences of using fossil fuels in the energy matrix, several studies investigate new and promising renewable energy sources. Among these sources, biomass has devoted scientists’ attention due to its versatility, availability, cost, and effect considered neutral for greenhouse gas emissions. In this context, this study presents a physicochemical and morphological evaluation of soybean husks for bioenergy production through thermochemical conversion processes. For examination of biomasses, X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR), Ultimate Analysis (UA), and Scanning Electronic Microscopy (SEM) analyzes were performed. For the XRD analysis, selected biomass presented a Crystalline Index (CI) of 38.41%. The sample revealed some functional groups such as alcohols, alkanes, alkenes, acids, amides, aromatics, and alkyl halides employing FTIR analysis. The ultimate analysis exhibited the amounts of carbon (41.81±0.92%), hydrogen (5.39±0.16%), nitrogen (1.00±0.09%), and oxygen (51.80±0.00%). The SEM images revealed the morphology and texture of soybean husks, which appear amorphous, disorganized, and porous, also showing structures that indicate the presence of hemicellulose, cellulose, lignin, protein, and other compounds. The studied biomass presented compositional, vibrational, structural, and morphological characteristics similar to other biomasses already used for bioenergy generation, demonstrating the excellent potential for thermochemical conversion, especially for direct combustion processes.
