RETRACTED: Hydrolysis of biomass using a reusable solid carbon acid catalyst and fermentation of the catalytic hydrolysate to ethanol

Influence of the acidity of solid catalyst HSO3-ZSM-5 on the hydrolysis of pretreated corncob

“…Among a variety of solid acid catalysts, sulfonated solid catalyst has also been studied widely. 2,3,5,[17][18][19][20][21][22][23][24] For examples, Akiyama et al 2 has successfully synthesized a polymer attached with porous sulfonic acid groups and applied it for cellulose hydrolysis reactions. The new catalyst possessed good resistance to vapor at high temperature; high acidity for the cellulose hydrolysis.…”

Cellulose Biorefinery Based on a Combined Catalytic and Biotechnological Approach for Production of 5‐HMF and Ethanol

“…As opposed to thermotolerant yeasts, the ethanol fermentation of biomass hydrolysates with common S. cerevisiae strains has been extensively studied. [70,71] Goswami et al [72] studied the process of S. cerevisiae fermentation on the catalytic hydrolysate of alkali-pretreated rice straw preliminarilyp urified with an ion exchange resin.…”

Enhancement of enzymatic saccharification of corn stover with sequential Fenton pretreatment and dilute NaOH extraction

“…Conversion of cellulosic materials into ethanol consists of pretreatment, enzymatic hydrolysis and fermentation steps (Goswami et al, 2015;He et al, 2015b;Talebnia et al, 2010). Pretreatment is considered to be a necessary process to break the lignin seal and disrupt the crystalline structure of cellulose (Choi et al, 2013;Fu and Mazza, 2011;He et al, 2014;Xu et al, 2010).…”
