     green bamboo was hydrolyzed over a range of durations at different temperatures. a simple pseudo-homogeneous irreversible first order kinetic model was developed to describe pentosan solubility during steam treatment of green bamboo. to avoid the influence of soluble pentosan during heating process, kinetic parameters were effectively dissolved based on the data in the reacting process. moreover, the pentosan solubility during heating process was also well modeled by numerical algorithm method. according to the origin of h factor, a modified parameter called steam treatment factor (f(p)) was proposed in this paper based on the determined kinetic constants. finally, residual pentosan in whole process could be predicted properly based on the f(p) and the introducing of potential hydrolysis degree (hd). after using f(p) to combine reaction temperature and time into a single factor, comparative result showed that steam treatment is more effective for removing pentosan compared with hot water extraction.
