摘要：This article put emphasis on systematic research and development on cellulose hydrolysis reactor. The simultaneous saccharification and fermentation of lignocellulosic was carried out in a 5-L reactor at high solids loading of corn stover (25%, w/w). The dynamic characteristics of reactive system were examined. The experimental results showed that the lignocellulosic biomass experienced a series of morphology evolution and viscosity variation. This evolution was a typical event caused by solid reactive processing, and it constituted the basis of a new geometrical configuration of reactor (specifically hybrid impeller). The minimum rotational speed of the impeller was proposed based on the Coutte flow analogy and the yield stress concept. The macroscopic performance of the reactor changed significantly with time. In view of this effect, the operating strategy of the impeller was determined.
