NOVELTY - Composition comprises lignin or lignin derivatives, a solvent and a carrier liquid; where the lignin or lignin derivatives constitutes at least 4 wt.% of the composition and where the lignin or lignin derivatives have a weight average molecular weight of not more than 5000 g/mol, and where the solvent comprises at least one alcohol, ether or organic ester, sulfoxide, ketone, aldehyde or its combination.    USE - The composition is useful for preparing fuel such as petrol and diesel, or diesel and petrol analogs, or biogasoline or biodiesel; or fuel additives. It can also be used for producing chemicals or paint. It can further be used as concreted grinding aid, set retarder for cement, strengthener of cement, antioxidant, enhancer of thermal protection, stabilizer in asphalt, emulsifying agent, fiber strengthening additive, cross-linking agent, board binder, anti-corrosion additive, wear resistant additive, antifriction additive, binder, emulsifier or dispersing agent, cross-linking or curing agent, or as a water absorption inhibitor or as a fluidization agent, as an antibacterial or anti-fungal surface or as a barrier, to impregnate wood or as an anti- corrosion agent (all claimed). Generally, the composition is used for refinery processes.    ADVANTAGE - A less complex method is provided to prepare biomass in order for it to be processed at a biorefinery, but also in order to process the lignin into fine chemicals or paint or paint additives for example. The method makes it easier or even facilitates production of fuel from biomass material.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a method of producing the composition which involves providing lignin or lignin derivatives having a weight average molecular weight of not more than 5000 g/mol; providing a solvent comprising at least one alcohol, ether, sulfoxide, ketone, aldehyde or ester or its combination, and a carrier liquid; and adding the lignin or lignin derivatives to the solvent and the carrier liquid to obtain a concentration of at least 4 wt.% and mixing; and    (2) a fuel obtained from the composition.
