First Claim
Patent Images
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.
