Abstract

The presently disclosed subject matter relates to a method and system of providing customized bioprocessing conditions for a variety of feedstock materials. Particularly, it has been surprisingly found that there is a correlation between the weight percent of lignin, cellulose, and/or hemicellulose and various reaction conditions. The weight percent lignin, cellulose, and hemicellulose are used to calculate indexes used to create a process index for sorting the feedstock into categories. A process adjustment factor can also be calculated and used to adjust the reaction conditions for each feedstock material.

Claim(s)

1 . A method of customizing reaction conditions for use in a reactor, based on a feedstock material, the method comprising: a. calculating the weight percent lignin (a), cellulose (b), and hemicellulose (c) in the feedstock material; b. calculating the lignin index (LI), cellulose index (CI), and hemicellulose index (HI) of the feedstock material according to the formulas LI=(a)/(1?a); CI=(b)/(1?b); HI=(c)/(1?c); c. calculating Process Index (PI) for the feedstock material according to the formula PI=LI×100; d. sorting the feedstock material into categories based on the PI; e. calculating a process adjustment factor (PAF) to adjust reaction parameters within each category according to the formula PAF=(LI/(CI+HI))×10; wherein the PI and PAF are used to calculate reaction conditions for bioprocessing the feedstock material; and wherein the reaction conditions are temperature, pressure, reaction time, weight percent NaOH.;
12 . A system for processing feedstock material, the system comprising: a. a reactor for processing feedstock material; b. customized bioprocessing reaction conditions based on the feedstock material; wherein the reaction conditions are generated by: calculating the weight percent lignin (a), cellulose (b), and hemicellulose (c) in the feedstock material; calculating the lignin index (LI), cellulose index (CI), and hemicellulose index (HI) of the feedstock material according to the formulas LI=(a)/(1?a); CI=(b)/(1?b); HI=(c)/(1?c); calculating Process Index (PI) for the feedstock material according to the formula PI=LI×100; sorting the feedstock material into categories based on the PI; and calculating a process adjustment factor (PAF) to adjust reaction parameters within each category according to the formula PAF=(LI/(CI+HI))×10; wherein the PI and PAF are used to calculate reaction conditions for bioprocessing the feedstock material; and wherein the reaction conditions are temperature, pressure, reaction time, weight percent NaOH.
