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, wherein the polymerized naphthalene sulfonate is a beta-naphthalene sulfonate formaldehyde condensation product;
- 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, 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, and the white liquor, excluding any recycled black liquor or wood moisture, is present in an amount of from 70 to 90 weight percent based on a total weight of the mixture.
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,
- wherein the polymerized naphthalene sulfonate has a molecular weight of from 6,000 to 8,000 g/mole.
