The Nondimensionalization of Equations Describing Enzymatic Cellulose Hydrolysis

The enzymatic hydrolysis is a very crucial stage in transforming lignocellulosic biomass to bioethanol. At the hydrolysis stage, two types of enzymes, which are EG and CBH , break the cellulose chains 1 1 into sugar in the form of cellobiose or glucose. This paper explores the current kinetic model...
