Abstract

The pretreatment of sugarcane bagasse (SCB) and rice straw (RS) using ionic liquids (IL) in combination with solid acid catalysts was investigated to enhance enzyme accessibility for biorefining. Both conventional hydrothermal and microwave-assisted treatments were carried out. Optimal conditions were determined in a microwave system using response surface analysis for cellulose digestibility, which was determined by the reducing sugar and glucose yield. The results demonstrate that SCB and RS fractionation in a choline acetate (ChOAc) IL catalyzed by SiO₂–OSO₃H in the microwave-assisted system and heterojunction metal oxides (SO₄²⁻/TiO₂/Fe₃O₄/WO₃) in the hydrothermal system significantly enhanced the cellulose digestibility. The costs of combined pretreatment and saccharification in the present study ranged from 0.60 to 1.48 €/g glucose for RS and 1.26–2.31 €/g glucose for SCB and were comparable to the previous studies.
