Lignocellulosic Biomass for Biofuel, Pretreatment Methods and its Application in Different Materials. A Review

LcBm is gaining popularity as an alternative energy source, due to the depletion of petroleum derivatives and environmental concerns.Characterizing Lcbm intermediates and products is critical for turning it into Bf.LBm chemical composition is crutial in creating successful pretreatment methods that break down its stiff structure and convert sucrose to glucose via enzymes and microorganisms.The steps herein reviewed allow for C2H5OH synthesis and additional value-added green chemicals.This review examines various feedstock and pretreatment techniques for C2H5OH production, including Ln degradation, breakdown, hydrolysis and fermentation.While combined pretreatment improves chemical production and enzymatic hydrolysis of LBm, it has greater operating costs.Acids pretreatment procedures, steam explosion and hydrothermal treatments effectively remove Hc fractions.Alkali, oxidative or organosolve pretreatment is more successful in removing and degrading phenols.The aim of this study was to improve the understanding of current and future bio refinery processes, identify constraints and develop technologies to improve pretreatment procedures.
