Abstract
A kinetic model was developed for predicting the time-dependent behavior of xylo-oligomer, xylose, arabinose, and furfural in hydrolysates during hot water preextraction of moso bamboo at various elevated temperatures. Due to the poor performance of conventional kinetic models for describing the autohydrolysis of moso bamboo, this model introduces the time dependence of the hydrogen ion concentration as an essential influencing factor. For each reaction, the activation energies and effect factor of hydrogen ion concentration on reaction rate coefficients were calculated using the proposed kinetic model. This model is helpful in the investigation of the dissolution and degradation of hemicellulose during hot water preextraction of moso bamboo and thus provides guidance for process control and optimization.
