METHOD FOR MIXED BIOMASS HYDROLYSIS

摘要

Methods and systems are disclosed for the hydrolysis of mixed biomass. The methods include forming a mixture of at least two modified biomass feedstocks to achieve various benefits, such as maximizing sugar yields and minimizing the formation of degradation products.

主权项

1. A hydrolysis method comprising:
(1) providing at least two modified biomass feedstocks comprising:
(a) from greater than 0 wt % to less than 100 wt % of a first modified biomass feedstock exhibiting a maximum hydrolysis yield at time X, when subjected to a first condition; and(b) from greater than 0 wt % to less than 100 wt % of a second modified biomass feedstock exhibiting a maximum hydrolysis yield at time Y, when subjected to the first condition;wherein:the second modified biomass feedstock is different from the first modified biomass feedstock;time X is less than or equal to time Y;and time X and time Y differ by less than or equal to about 100% of time X; and (2) subjecting a mixture of the first modified biomass feedstock and the second modified biomass feedstock to the first condition to achieve a maximum hydrolysis yield at time Z, wherein time Z is less than time Y; wherein: the hydrolysis method is performed at a pH of at least 1.3; and all weight percent values are on a dry basis and are based on the total weight of the at least two modified biomass feedstocks.
