Abstract

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. tradução do resumo resumo patente de invenção: "sistema e método para aumentar concentração de carboidrato e lignina no pré-tratamento de hidrolisado de biomassa". trata-se de um sistema e método para pré-preparar biomassa. o fluxo de passagem de contracorrente e hidrolisado reciclado são empregados para pré-tratar a biomassa. as concentrações de carboidrato e lignina no hidrolisado final são amentadas. os ingredientes de temperatura no vaso de pré-tratamento podem ser usados para aumentar a eficiência de pré-tratamento. reciclando-se o calor e o líquido, os métodos revelados ajudam a reduzir a energia e/ou água usada nos processos.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.
