Microstructural and FT-IR analysis of some raw biomass used as solid biofuels

Abstract

This article focuses on examining the morphological structure and characteristics of three typically cultivated biomasses in Moldova, on both the left and right banks of the Prut River: lean, white buckthorn, and miscanthus. Utilizing scanning electron microscopy (SEM Quanta 200 3D), X-ray analysis (Xpert PRO MPD), and FT-IR, the biomass was evaluated accordingly. All wood samples were subjected to a chemical examination that included the morphological aspect and the measurement of extractive compounds, lignin concentration, and hemicellulose content.
