OPTIMIZATION OF HYDROTHERMAL PRETREATMENT PARAMETERS FOR GLUCOSE AND XYLOSE RECOVERY FROM POPPY STALKS

摘要

Response surface methodology (RSM) was employed to optimize hydrothermal pretreatmentrnconditions for glucose and xylose recovery from poppy stalk, with respect to temperature (120-200℃), solid to liquidrnratio (0.05-0.20) and pretreatment time (5-60 min). While experimental maximum glucose recovery of 628.20 mgrnglucose/g initial cellulose was achieved at condition of 200 ℃, 0.200 g/ml of solid to liquid ratio and 32.5 min,rnmaximum experimental xylose recovery (130.12 mg/g initial xylose) was at the conditions of 160 ℃, 0.125 g/ml ofrnsolid to liquid ratio and 32.5 min.
