Processes for obtaining substances from bark, especially bark high in suberin and lignin, which substances can be used for preparing biofuels are disclosed. The processes use a solvent system for dissolving the substances, which system can be recycled in the process. The solvent system comprises a base selected from tertiary aliphatic amines A composition comprising bark and the solvent system, which can be used in the processes, is also disclosed.

Processes for obtaining substances from bark and a composition containing bark for use in the processes

The present invention relates to a composition and a method of preparing the composition where the composition comprising functionalized lignin having a weight average molecular weight (M) of at least 1,000 g/mol and a green carrier liquid comprising depolymerized functional lignin, wherein the functionalized lignin is dissolved in the green carrier liquid and wherein the amount of depolymerized functionalized lignin compounds in the composition is higher than the amount of functionalized lignin.

Continuous production of fuel grade hydrocarbons by hydrotreatment of functionalized lignin

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.

Polymeric material comprising modified lignin

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. The composition may be used for preparing fuels or lubricants.

Composition comprising esters of lignin and oil or fatty acids

The present invention relates to a composition comprising lignin and a solvent where the lignin is functionalized with an ether group.

Composition comprising derivatized lignin for fuel production

Ether functionalized lignin for fuel production

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.

A method of obtaining depolymerized lignin from biomass using a transition metal catalyst and a solvent mixture of organic solvent and water. The invention further relates to a composition obtainable by the method and the production of fuel.

Depolymerisation of lignin in biomass

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.

The present invention relates to a composition and a method for preparing said composition where the composition comprises a lignin, a solvent, a carrier liquid, and a fatty acid, wherein the lignin constitutes at least 4 weight % of the composition and has a weight average molecular weight of not more than 5,000 g/mol, wherein the solvent is an alcohol, ether, organic ester, sulfoxide, ketone, aldehyde or a combination thereof, and wherein the carrier liquid is a hydrocarbon oil.

Compositions of biomass materials for refining

The present invention relates to a method of cleaving a &#x3b2;-O-4 bond to the corresponding C&#x2014;H bond in a substrate, by use of a hydrogen donor and a metal catalyst in a solvent. Thereby it is possible to depolymerize a polymer having a repeating &#x3b2;-O-4 bond.

Catalytic reductive cleavage of a &#x3b2;-O-4 bond of ethers or polyethers such as lignin

The present invention relates to a method of reducing a C&#x2014;O bond to the corresponding C&#x2014;H bond in a substrate which could be a benzylic alcohol, allylic alcohol, ester, or ether or an ether bond beta to a hydroxyl group or alpha to a carbonyl group.

Reduction of C&#x2014;O bonds by catalytic transfer hydrogenolysis

A method of improving a strength property of a sheet-formed fibrous material formed from an aqueous slurry of cellulose fiber, including coating at least one face of the material with a coating formulation including a polysaccharide containing at least two carboxylic groups and low molecular weight organic mono-, di- or poly-carboxylic acid in an aqueous carrier, keeping the coated face at a temperature of 50&#xb0; C. or more for a time sufficient to obtain the desired improvement including drying of the material.
