Conversion of Glucose and Xylose to 5-Hydroxymethyl furfural, Furfural, and Levulinic Acid Using Ethanol Organosolv Pretreatment under Various Conditions

Abstract

http://www.woodj.org -475 - INTRODUCTIONCellulose is a natural polysaccharide that is composed of glucose units linked by β-1,4-glycosidic bonds. Glucose is the predominant constituent of lignocellulose biomass, and it is a potential and sustainable resource that can be used for the production of useful chemicals and fuels (Hwang et al., 2021;Iswanto et al., 2021;Zhang et al., 2016). Cellulose and lignocellulosic biomass are hydrolyzed and depolymerized into glucose under conditions of thermal reactions conducted in aqueous and organic solvents in the presence or absence of catalysts

Conversion Characteristics of Chemical Constituents in Liriodendron tulipifera and Their Influences on Biomass Recalcitrance during Acid-Catalyzed Organosolv Pretreatment

“…Over 170℃, the total glucose yields rapidly increased as a result of the rapid hydrolysis of glucan in L. tulipifera (Table 3). To understand the conversion characteristics of glucan and xylan, comparisons were made with the hydrolysis and conversion of cellulose and xylan standards (Gwak et al, 2022).…”

Glucaric Acid Production from Miscanthus sacchariflorus via TEMPO-Mediated Oxidation with an Efficient Separation System

“…For instance, glucose derived from the enzymatic hydrolysis of cellulose could be converted to value-added chemicals such as 5-HMF 14 or levulinic acid. 15 Xylose and xylose oligomer could be valorized by converting xylose to furfural, 16 which is widely applied to resin, 17 solvent, 18 and biofuel 19 by further conversion. Lignin which is a natural aromatic compound could be applied to various industrial fields including biocomposites, 20 bio-oil by pyrolysis, 21 and aromatic compounds such as vanillin.…”

“…All biomass components produced from the biorefinery process could be valorized by a further conversion process. For instance, glucose derived from the enzymatic hydrolysis of cellulose could be converted to value-added chemicals such as 5-HMF or levulinic acid . Xylose and xylose oligomer could be valorized by converting xylose to furfural, which is widely applied to resin, solvent, and biofuel by further conversion.…”
