Abstract:
The invention relates to a process for making a purified lignin composition comprising a carrier liquid suitable for processing in a refinery. It comprises providing an aqueous lignin composition comprising lignin, cooking chemicals and water and adding a carrier liquid to the aqueous lignin to provide an organic phase. Then all or substantially all the water is removed from the composition. The lignin composition is processed to make the lignin more soluble in the carrier liquid in order to transfer more of the lignin to the organic phase. Cooking chemicals are removed, suitably by of washing by liquid/liquid extraction using a washing liquid. Finally washing liquid is removed.
Abstract:
The present invention relates to a composition and a method of preparing the composition where the composition comprises lignin dissolved in depolymerized lignin obtained from hydrotreatment of lignin. The method may be operated in batch mode or in a continuous mode but there is no need to add any oil.
Abstract:
The present invention relates to a composition comprising a carrier liquid and lignin or lignin derivatives solubilized in said carrier liquid; wherein at least one of the hydroxyl groups of the lignin or lignin derivatives have been substituted with ester groups forming esterified lignin or lignin derivatives. The composition may be used for preparing fuels or lubricants.
Abstract:
A polymeric material comprising a first polymer and a second polymer where the first polymer is a natural or a synthetic polymer and the second polymer is modified lignin. The modified lignin is modified with an alkyl containing group via linker wherein the linker is an ether group and wherein the alkyl containing group is derived from fatty acid methyl ester.
Abstract:
The present invention relates to a composition comprising a carrier liquid and lignin or lignin derivatives; wherein at least one of the hydroxyl groups of the biomass have been substituted with ester groups and wherein the carrier liquid is a gas oil. The composition may be used for preparing fuels or lubricants.
Abstract:
A method of extracting lignin from an aqueous composition by either treating the composition with a solvent and heat, or by acidifying the composition in order to induce phase separation.
Abstract:
The present application relates to a solid material of crosslinked lignin where the lignin is crosslinked using polyunsaturated fatty acids, a composition and a method of preparing the solid material.
