Transport and Conversion Characteristics in a Microreactor Loaded With Cellulase
The microreactor loaded with cellulase can efficiently convert cellulosic biomass to pre-pare glucose and provide feedstock for subsequent microbial energy conversion.In this paper,ex-perimental and simulation studies on the enzymatic saccharification of CMC were conducted in a microreactor loaded with cellulase to obtain the influence of the inner surface structure on the mass transfer and enzymatic reaction.The simulation results showed that compared to the inner surface structures such as equilateral triangles and semicircles,the setting of a high rectangular structure promotes glucose production in the microreactor more significantly.Besides,the microreactor with high rectangular structures can obtain the highest outlet glucose concentration per unit pressure drop,which is conducive to practical application.Compared with increasing the surface structure size,decreasing the structure spacing has a better enhancement effect.Under the optimal surface structure parameters,the outlet average glucose concentration enhancement rates were all higher than 7.0％for the enzymatic reactions at different viscosities.
