The present invention relates to an improved process for preparing an aqueous dispersion of lignin and the use of said suspension in the preparation of a resin.

Process for preparing a resin

Process for preparing a lignin-based resin

The present invention relates to a liquid lignin composition, particularly useful in the manufacture of resins for products such as insulation, laminates and engineered wood products such as oriented strand boards (OSB). The liquid lignin composition has a low viscosity even at low water content.

Liquid lignin composition comprising lignin, water, alkali and urea

The present invention is directed to a process to produce agglomerated lignin with a controlled particle size distribution. The agglomerated lignin is essentially free of dust so that the risk of dust explosion is greatly reduced.

Process for producing agglomerated lignin and use thereof

The present invention relates to a lignin-based phenolic resin, particularly useful in the manufacture of oriented strand boards (OSB).

Lignin-based phenolic resin

The present invention relates to a method for increasing the reactivity of lignin which method comprises the following steps; providing a mixture comprising lignin and an alkali solution wherein the concentration of the alkali solution of the mixture is between 5-50% by weight, storing said mixture for a period of at least 1 day whereby the reactivity of the lignin is increased. The present invention also relates to a resin composition comprising said lignin and use of said resin composition.

Method for increasing the reacitivity of lignin, and a resin composition comprising said lignin

The present invention relates to an activated lignin composition, its manufacture and its use thereof. It also relates to a resin comprising lignin, its manufacture and use.

Activated lignin composition, a method for the manufacturing thereof and use thereof

The present disclosure relates to a thermally reactive thermoplastic intermediate product, in the form of a shaped body, wherein the intermediate comprises a composition, wherein the composition comprises a purified or optionally unpurified softwood lignin and at least a first additive.

Thermally reactive thermoplastic intermediate product and method of manufacturing thereof

The present invention relates to a liquid lignin mixture comprising 3-50 wt % methanol, 12-50 wt % lignin and 5-85 wt % aqueous alkali solution wherein the concentration of said aqueous alkali solution is 1 to 50 wt % of alkali in water, based on the weight of said alkali solution prior to mixing with the other components of the mixture. The liquid lignin mixture can be used to manufacture lignin-based phenolic resins, which are particularly useful in the manufacture of laminates.

Liquid lignin composition, lignin-based resin, and method of increasing the solubility of lignin

The present invention relates to a composition for coating, in particular a composition comprising lignin and one or more epoxy-group containing compounds, and methods for the manufacturing thereof and uses thereof. The present invention also relates to products obtainable by said methods and uses thereof.

Composition comprising lignin and epoxy compound for coating and method for the manufacturing thereof and use thereof

The present invention relates to a composition comprising a lignin polyol, a method for the manufacturing of said composition and use thereof in different application areas, such as in adhesives, binders, castings, foams (such as in rigid polyurethane and polyisocyanurate foams for thermal insulation and construction applications, semi-rigid, flexible, moulded, laminated, microcellular and viscoelastic polyurethane foams), fillers, glues, sealants, elastomers and rubbers. The present invention also relates to a method for the manufacturing of a foam and use of this foam.

Composition in the form of a lignin polyol, a method for the production thereof and use thereof

A method to increase the molecular weight of wood mannans and xylans comprising aromatic moieties comprises the steps: a) obtaining mannan and/or xylan from wood, b) subjecting the mannan/xylan to oxidizing conditions to convert at least a fraction of the aromatic groups into radicals and reacting said radicals with each other to obtain complexes of mannan/xylan with increased molecular weight. The method is easy and cost efficient and enables to upgrade small wood mannans and xylans that are important in the pulp and paper industry into larger mannans and xylans and more defined structures which makes their isolation easier and application areas broader. Another advantage is that separation of mannans and xylans from mannans and xylans with bound aromatic groups is provided. The wood mannans and xylans with increased molecular weight can be used for the manufacture of barrier films in packages, for instance for oxygen, liquids and gas.
