AB In this work, the thermal decomposition of exhausted sugar beet pulp (ESBP) at a heating rate of 10 C min-1 and theresulting evolved gases were examined by thermogravimetric (TG) analysis coupled with Fourier transform infrared(FTIR) spectroscopy. The results obtained in the identification of biomass fiber components were compared with those ofthe Van Soest method. The TG curves obtained in the fast thermal pyrolysis of ESBP exhibited substantial mass loss peaksprimarily associated with the decomposition of pectin, hemicellulose and cellulose at 233, 269 and 341 C, respectively.Lignin, however, was more difficult to decompose since its mass loss occurred over a broad temperature range(200–800 C). The FTIR spectra obtained at these temperatures were consistent with the formation of large amounts ofgases such as CO2, CO, H2O and CH4 in addition to a mixture of organic products including aldehydes, ketones, organicacids, alkanes and phenols. Based on these results, the proposed approach allows lignocellulosic components in exhaustedsugar beet pulp biomass to be efficiently screened. Also, the new approach is faster, operationally simpler and moreeconomical than the Van Soest method.
