摘要：

A model based on the shrinking particle theory is developed for the rate of enzymatic hydrolysis of natural impure cellulosic wastes with a product concentration present in the start of the reaction. The enzymatic hydrolysis of some waste materials (rice pollards) has been studied in a batch stirred reactor at 50 degrees C. A comparison between the experimental data for diverse reaction systems and those predicted from the model, demonstrated the applicability of the latter. The average mean absolute deviation was about 10.0%. (C) 2005 Elsevier B.V. All rights reserved.
