摘要: Abstract With heating rates of 20, 50 and 100 K min −1 , the thermal decomposition corn straw samples (corn stalks skins, cores, bracts leaves) were studied using thermogravimetric analysis. The maximum pyrolysis increased with rate increasing temperature at peak also increased. Assuming addition three independent parallel reactions, corresponding to pseudocomponents linked hemicellulose, cellulose lignin, two different three-pseudocomponent models used simulate pyrolysis. Model parameters given. It was found that model n -order kinetics more accurate than first-order most cases. showed describe hemicellulose.
