Abstract: The present invention relates to a method for production of a fuel composition, more specifically a middle distillate fuel composition, and a composition—in particular a co feed composition comprising a furanyl containing oligomerisation composition admixed with one or more material component comprising fatty acids or fatty acid derivatives and the use of such composition.

Abstract: A process for oligomerizing olefinic, lower hydrocarbons. The process comprises the steps of feeding a fresh olefinic hydrocarbon feedstock to a reaction zone; contacting the olefinic hydrocarbons of the feedstock with an acidic catalyst in the reaction zone in order to dimerize at least a part of the olefinic hydrocarbons, withdrawing an effluent containing oligomerized olefins from the reaction zone; and conducting the effluent to a separation zone, wherein the oligomerization reaction product is separated from said effluent. According to the invention, the reaction is carried out in homogeneous phase comprising a solvent for olefinic hydrocarbons, maintained at supercritical conditions. By using supercritical carbon dioxide as a solvent deactivation rate of catalyst can be diminished. Carbon dioxide is easy to remove from the product mixture and spent reaction medium can be used for regeneration of the catalyst.
