Impact of Alkaline Pretreatment Condition on Enzymatic Hydrolysis of Sugarcane Bagasse and Pretreatment Cost

A combined severity factor (RCSF) which is usually used to evaluate the effectiveness of hydrothermal pretreatment at above 100 °C had been developed assess influence temperature, time, and alkali loading on enzymatic hydrolysis lignocellulose. It not suitable for evaluating alkaline lower than °C. According reported deducing process, this study modified expression $$ {R}_{\mathrm{CSF}}=\log \left[{C}_{OH^{-}}^n\times t\times {e}^{\left({T}_r-{T}_b\right)/14.75}\right] as \left\{{C}_{OH^{-}}\times {e}^{\left[-13700/\left( Tr+273\right)+36.2\right]}\right\} easier more reasonable pretreatment. showed that RCSF exhibited linear trend with lignin removal, quadratic curve relation efficiency (EHE) same temperature. The EHE alkali-treated SCB could attain maximum value RCSF, indicated it was necessary continuously enhance strength improving EHE. Within a certain temperature range, important time Furthermore, contribution cost seldom concerned investigated in work. contributed 70% cost. This laid foundation further optimizing reduce its practical application.
