Pulping With Organic Compounds TRIZ Cases

Chemical delignification removes lignin and hemicellulose from plant material to extract intact cellulose macrofibers with higher strength.

Chemical delignification removes lignin and hemicellulose to extract intact cellulose macrofibers with higher strength for composite reinforcement.

Removing lignin from reed or bamboo opens micropores and enlarges lumina, boosting fluid transport and evaporation in passive evaporators.

Adding a lignin precursor and short-chain polyol during cooking blocks lignin condensation, improving pulp brightness while reducing bleaching chemicals.

Drying, desolventizing, centrifugation, and staged evaporation recover organic acids, cut caustic use, and improve lignin and juice processing.

Drying, desolventizing, distillation, and centrifugation recover organic acids and lignin from pretreated plant materials while cutting water and alkali use.

A phenyl tetracarboxylic acid and macromolecule polymer blend improves kraft pulp viscosity and yield while reducing rejects.

Dryer, desolventizer, and distillation stages recover organic acids for reuse, while lignin separation and stillage valorization reduce process waste.

An acidic sulfuric acid, alkanesulfonic acid, and peroxide composition removes lignin while preserving cellulose at mild conditions.

A surfactant blend improves cooking-liquor wetting and lignin dissolution, reducing rejects during lignocellulosic digestion.

Using ionic liquids to dissolve lignocellulosic biomass separates cellulose and lignin into enriched fractions without environmentally unfriendly solvents.

Modified Caro's acid oxidizes lignin in biomass at low temperatures, while caustic treatment dissolves hemicellulose to prevent toxic byproduct formation.

Ternary cooking liquor removes residual lignin to produce high-whiteness pulp without bleaching.

Disc refining with chemical treatment prevents hornification and self-bonding, enabling efficient dispersion of fibrous materials in aqueous systems.

A method for producing densified cellulosic material by delignifying entire wooden blocks before applying compression and shear forces.
