system and method for increasing carbohydrate and lignin concentration in biomass hydrolyzate pretreatment

摘要

abstract a system and method are disclosed for pretreating biomass. countercurrent flowthrough and recycled hydrolysate are employed to pretreat the biomass. the concentrations of carbohydrate and lignin in the final hydrolysate are increased. temperature ingredients in the pretreatment vessel may be used to increase the pretreatment efficiency. by recycling the heat and the liquid, the disclosed methods help reduce energy and / or water used in the processes. patent system and method for increasing carbohydrate and lignin concentration in the pretreatment of biomass hydrolyzate. It is a system and method for pre-preparing biomass. Countercurrent flow and recycled hydrolyzate are used to pretreat the biomass. Carbohydrate and lignin concentrations in the final hydrolyzate are increased. Temperature ingredients in the pretreatment vessel can be used to increase pretreatment efficiency. By recycling heat and liquid, the disclosed methods help to reduce the energy and / or water used in the processes.
