Effects of formaldehyde on fermentable sugars production in the low-cost pretreatment of corn stalk based on ionic liquids
文献摘要：
Low cost processing of lignocellulosic biomass is of great importance for sustainable chemistry and engi-neering.Herein,a low cost system composed of 1-butyl-3-methylimidazolium chloride([C4C1im]Cl),HCl and formaldehyde(FA)was developed for the pretreatment of corn stalk at 80℃.The efficiency of this technology was compared with that in dioxane system or without FA addition.Due to FA stabilization,the extent of acid-hydrolysis of carbohydrate fraction can be significantly decreased while 70％above of lignin was removed with the pretreatment of[C4C1im]Cl/HCl/FA system at 80℃for 2 h.A maximum reducing sugar yield of 93.7％and glucose concentration of 7.0 mng·ml-1 were subsequently obtained from enzymatic hydrolysis of the slurry.There were great differences in compositions of small molecule degraded products obtained with FA addition or not.The present[C4C1im]Cl based system exhibits great potential of substituting volatile organic solvents(i.e.dioxane)in developing low cost lignocellulosic bio-mass pretreatment at low temperature.Also,this work would gain insight into understanding on the roles of stabilization methods on the economic improvement of IL based biomass processing.
