In the present study, enzymatic hydrolysis at high solid loadings (<20% WIS) was investigated using different impeller types. In addition to sugar yields, impeller torques (and hence power input) were monitored throughout the hydrolysis to compare the suitability of the impeller type for this process. Furthermore, it was possible to control the power input at a fixed set-point value throughout the hydrolysis period by adjusting the stirrer speed. This enables a proper comparison between the different impellers based on an energy input basis. The factors affecting high solid hydrolysis will be discussed.
