There are many different ways to convert cellulose to bioethanol. But enzymatic hydrolysis makes ethanol produced from mass-produced plant materials economically comparable to other liquid fuels. In the past, acid hydrolysis has been widely used in the process of converting cellulose to ethanol. However, due to the great potential of the enzymatic hydrolysis process and the advantages that this process has over other methods, this method has attracted a lot of attention today. Most recent research on the process of converting cellulose to ethanol is based on the enzymatic process. Due to the impermeable physical structure of lignin in lignocellulosic materials as well as the crystalline structure of cellulose, enzyme access to cellulose molecules is simply not possible and the reaction rate is low. The aim of this study was to describe a kinetic model related to the hydrolysis of cellulose materials by the enzyme cellulase. Examining the quantitative and qualitative parameters related to this model will enable researchers to make workable suggestions in future research. It should be noted that the results of this model were closely consistent with the experimental results and the accuracy of the proposed model was acceptable.
