A SOLID OR CONCENTRATED LIGNOCELLULOSIC HYDROLYSATE AND METHODS TO PREPARE THE HYDROLYSATE FROM PRETREATED LIGNOCELLULOSIC BIOMASS

摘要

The present disclosure provides a solid lignocellulosic hydrolysate and methods to prepare the solid lignocellulosic hydrolysate from a woody biomass or an herbaceous biomass. The solid lignocellulosic hydrolysate allows for ease of storage, ease of transportation and handling, as well as ease of use in biological or fermentation processes or chemical processes for the production of biofuel, bioproducts, chemicals and food products due to the bulk handling characteristics (e.g., solubility and rate of dissolution) of the solid hydrolysate. The present disclosure also provides a method to prepare a concentrated hydrolysate from lignocellulosic biomass that been pretreated. The concentrated hydrolysate may be used in the production of biofuel, bioproducts, chemicals and food products, or may be further processed into a solid hydrolysate.
