Question

Literature review of physical and chemical pretreatment processes for lignocellulosic biomass

Answer 1

Answer:

Pretreatment with acid hydrolysis (HCl, H2SO4), can result in improvement of enzymatic hydrolysis of lignocellulosic biomass, to release fermentable sugars. ... Acid reagents, such as H2SO4, HCl, and CH3COOH, at concentrations of 1, 2, and 4% (w/w) have been used for pretreatment.

Pretreatment Processes for Lignocellulosic ...

Pretreatment technologies for lignocellulosic biomass include biological, mechanical, chemical methods and various combinations thereof. The choice of the optimum pretreatment process depends very much on the objective of the biomass pretreatment, its economic assessment and environmental impact.
