A Mathematical Model For The Effects of Volume Fraction and Fiber Aspect Ratio of Biomass Mixture During Enzymatic Hydrolysis

Renewable energy or biofuel from lignocellulosic biomass is an alternative way to replace the depleting fossil fuels. The production cost can be reduced by increasing the concentration of biomass particles. However, lignocellulosic biomass is a suspension of natural fibres,...
