The main constituents contained in biomass include hemicellulose, cellulose and … constituents, including hemicellulose, cellulose, lignin, xylan and dextran, were individually torrefied in a thermogravimetry. Two … the blend of hemicellulose, cellulose and lignin at the three torrefaction temperatures were also examined. The weight …
