Eucalyptus residue was employed as a biomass raw material for the hydrothermal pretreatment process for the enzymatic hydrolysis. The flow type reactor system made it possible to shorten the heating and cooling times, compared with the batch reactor system. Pulverized eucalyptus residue was treated in the temperature range of 140-275 ℃ in both systems. The glucose content of the treated liquid product was measured. The solid product was analyzed for cellulose content and further treated with cellulase. The product glucose yield indicated the effectiveness of the hydrothermal pretreatment. A reaction network model for the hydrothermal pretreatment was proposed and applied successfully. The flow rate was varied from 20 to 100 mL/min for flow-type reactor. The effect of the reaction temperature and the flow rate was measured.
