Extraction of valuable components from bark

The present invention relates to a process for the extraction of valuable components from a tannin-rich bark raw-material, by carrying out an alkaline cooking step, followed by acid precipitation to separate the valuable components from the remaining bark pulp. The invention also relates to the use of said process on a bark side stream of a chemical pulping plant, whereby the liquor remaining after the extraction of the present process is returned to a stream of the wood pulping process, typically to a black liquor stream, while the spent pulp can be processed further, e.g. by bleaching to give dissolved pulp.

AQUEOUS ALKYD DISPERSIONS WITH IMPROVED APPLICATION PERFORMANCES IN TERMS OF RESISTANCE TO BLOCKING AND YELLOWING, HARDNESS DEVELOPMENT AND SHINE
20210371647 · 2021-12-02 ·

The present invention relates to aqueous alkyd resin dispersions comprising a) a short oil alkyd resin comprising, in its fatty acid component a1), at least one polyunsaturated fatty monoacid a11) having at least two unsaturations per molecule and comprising at least 35% by weight of a monoacid a111) having conjugated unsaturations, the content by weight of said fatty monoacid a111), with respect to said alkyd resin, being at least 5%, preferably from 5% to 40% and more preferably from 5% to 35%, and b) at least one anionic phosphate surfactant. The invention also covers a preparation process and its use in decorative coatings. The coatings based on these aqueous dispersions exhibit improved performance qualities in resistance to blocking and yellowing, in development of hardness and in gloss.

POST-HARVEST METHOD FOR NATURAL FIBER NANOPARTICLE REINFORCEMENT USING SUPERCRITICAL FLUIDS

A method of forming a composite material includes disposing dried plant material, nanoparticles, and a supercritical fluid in a vessel. A cellular structure of the dried plant material expands when disposed in the supercritical fluid and the nanoparticles migrate into and are embedded within the expanded cellular structure of the disposed dried plant material. The disposed dried plant fibers with embedded nanoparticles are removed from the vessel and mixed with a polymer to form a polymer-nanoparticle mixture. A chemical additive can be added to the supercritical fluid and the chemical additive can remove at least one of hemicellulose, lignin and pectins from the dried plant material.
