The present research work deals with the evaluation of greater liberation of total and reducing sugars from three lignocellulosic residues (rice husk, sugar cane residues and corn residues) pretreated and then hydrolyzed with cellulolytic enzymes. The residues were subjected to pretreatments with different solutions delignificants in a solid:liquid ratio of 1:10 for a time of three hours at a temperature of 70ºC. The alkaline pretreatment for the three lignocelullotic residues was the one released the greatest amount of total sugars. The enzymatic hydrolysis was carried out using the Cellic CTec 2 enzymatic complex, which was incubated for 72 hours at 50 º C, the percentage of enzyme to be worked, was varied according to the weight of the material pretreated with the different delignificants solutions and selected in the previous stage; in this stage, the release of a greater quantity of reducing sugars was evaluated. The results obtained from reducing sugars in rice husk were 19300.85 ppm, sugarcane residues of 29829.42 ppm and corm residues of 20663.79 ppm; in all three cases, the residues were pretreated in alkaline conditions, the incubation days of the enzymatic hydrolysis varied according to the residues, the rice husk was incubated for 72 hours, the sugarcane residues for 48 hours and the corn residues for 24 hours. Finally, based on the hydrolysis selected, they were semi-pilot scaling, in which values of reducing sugars were obtained: : 19048.26 ppm, 25147.28 ppm y 22989.73 ppm for rice hus, sugarcane residues and corn residues, respectively.
