Analysis of Pennisetum americanum pyrolysis process based on the technique of thermo-gravimetric analysis coupled with infrared spectroscopy
摘要
Abstract
Pennisetum americanum pyrolysis behavior and mechanism were studied at a slow heating rate by thermo-gravimetric (TG) analysis coupled with fourier transform infrared spectroscopy (FTIR). The results showed that the decomposition of P. americanum mainly occurred at the temperature range of 220 to 500 ?. The weight loss became quite slow when temperature further increased over 500 ? and the amount of residue finally decreased to 5. 33 % . FT-IR analysis showed that there were carbon dioxide, carbon monoxide, alkane, aldehydes, acids produced during the P. americanum pyrolysis process. Based on the TG curve and infrared spectra, P. americanum pyrolysis kinetic was studied. P. americanum pyrolysis process was divided into three stages, corresponding with 301. 51, 88. 39 and 330. 58 kj/mol for activation energy respectively.关键词
