Abstract
A method for digesting lignocellulosic material includes combining a lignocellulosic material comprising lignocellulosic biomass, a polymerized naphthalene sulfonate, a sodium xylene sulfonate, and a white liquor comprising sodium hydroxide and sodium sulfide to form a mixture. Further, the method includes heating the mixture to digest at least a portion of the lignocellulosic material.

A method for digesting lignocellulosic material, the method comprising:
- combining a lignocellulosic material comprising lignocellulosic biomass, a polymerized naphthalene sulfonate, a sodium xylene sulfonate, and a white liquor comprising sodium hydroxide and sodium sulfide to form a mixture;
- and
- heating the mixture to digest at least a portion of the lignocellulosic material.
A method for digesting lignocellulosic material, the method comprising:
- combining a lignocellulosic material comprising lignocellulosic biomass, a dispersant, a penetrant, and a white liquor comprising sodium hydroxide and sodium sulfide to form a mixture;
- and
- heating the mixture to digest at least a portion of the lignocellulosic material, wherein the mixture has a dispersant to penetrant ratio of from 10:90 to 90:10, and the mixture has a combined total content of the dispersant and the penetrant of from 0.1 to 10 kg per metric ton of dry lignocellulosic material.
A mixture comprising:
- lignocellulosic material comprising lignocellulosic biomass present in an amount of from 10 to 30 weight percent based on a total weight of the mixture;
- white liquor comprising sodium hydroxide and sodium sulfide and present in an amount of from 70 to 90 weight percent based on a total weight of the mixture;
- a dispersant;
- and
- a penetrant;
- wherein the dispersant and the penetrant are present in the mixture in a weight ratio of actives from 10:90 to 90:10, respectively;
- and
- wherein a combination of the dispersant and the penetrant is present in an amount of from 0.1 to 10 kg actives/metric ton dry lignocellulosic material.
