摘要: An effective pretreatment to improve cellulose accessibility and facilitate glucose release is crucial in a cellulosic ethanol biorefinery. This work comparatively assessed four H2O2-involved pretreatments, i.e., concentrated H3PO4 plus H2O2 (PHP), H2O2–CH3COOH (HPAC), alkaline-H2O2 (AHP), Fenton chemistry (FC), for their performances on wheat straw, poplar, birch biomass. Substrate characteristics before after were using SEM, XRD, LSCM. The hydrolytic potentials of the pretreated substrates compared by Simons’ stain cellulose–glucose conversion assessment. results showed that acidic pretreatments (PHP HPAC) more efficient biomass delignification AHP FC. PHP promising production due its corresponding high yield (368.0 mg g−1) enzymatic hydrolysis.
