Effects of Pyrolysis Conditions on Structural Ingredients and Functional Groups of Hybrid Poplar

Abstract

In this study, thermal behavior and the functional group distributions of structural ingredients of biomass were investigated under pyrolytic conditions. An energy-forestry tree (hybrid poplar) was used as biomass material. Macromolecular ingredients in this biomass such as holocellulose (hemicellulosics + celluloses) and lignin were isolated chemically using several analytical techniques. Thermal analysis, X-ray Diffraction (XRD), X-ray Fluorescence (XRF), BET surface area, Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM) techniques were applied to specify the biomass and its ingredients.
