Enzymatic hydrolysis of lignocellulosic biomass is an attractive method for sustainable cellulosic ethanol production. Given the complex lignin-cellulose-hemicellulose network of lignocellulosic biomass, enzymatic hydrolysis is a complicated heterogeneous catalytic process. This work is the first to comprehensively analyze the research progress of enzymatic hydrolysis (including pretreatment, enzyme adsorption, and enzymatic hydrolysis) using both experimental and theoretical model evidence. The mechanism and the main influencing factors of the hydrolysis process were revealed. The appropriate method and suitable reaction conditions of enzymatic hydrolysis were proposed. This work also analyzed the relationship between experimental and modeling studies, which supports optimizing the hydrolysis parameters and advancing enzymatic hydrolysis development in industrial applications.
