Influence of Mineral Acid, Hydrotropic Organic Acid, and ChCl–pTSA Binary Catalyst on Organosolv Fractionation of Pigeon Pea (Cajanus cajan) Stalk
Lignocellulosic biomass recalcitrance remains a major challenge for the development of integrated biorefineries, necessitating efficient and selective pretreatment strategies. In this study, the influence of three acid catalyst systems, namely sulphuric acid (mineral acid), p-toluenesulphonic acid (pTSA; hydrotropic or...
