In order to enhance the efficient utilization of corn straw,it is crucial to overcome its'refractory nature'and dismantle it effectively.This study utilized dilute sulfuric acid in combination with ethylene glycol to efficiently break down corn straw,investigating the impact of pretreatment temperature,duration,and solvent concentration on deconstruction.Additionally,the study examined how structural changes in corn straw affect enzymatic hydrolysis efficiency.The findings revealed that a mixture of 0.7%sulfuric acid and 50%ethylene glycol yielded the most effective deconstruction results at 180℃for 30 minutes,resulting in a cellulose retention rate of 82.51%,hemicellulose removal rate of 70.15%,and lignin removal rate of 46.62%.Structural analysis indicated that the deconstructed corn straw exhibited a rough surface and increased specific surface area,potentially enhancing cellulase accessibility and enzymatic hydrolysis efficiency.This research offers valuable insights into the efficient deconstruction of corn straw and the optimization of resource utilization.
