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.
Claims12
A method for production of a fuel composition, the method comprising:
- a) oligomerisation of 2-methylfuran (2-MF) using an acidic catalyst resulting in a furanyl containing oligomerisation composition having at least 70 wt. % oligomers selected from the group consisting of trimers, tetramers and pentamers of 2-MF having from 2 to 4 furanyl moieties;
- b) optionally admixing one or more material components containing fatty acids or fatty acid derivatives to the furanyl containing oligomerisation composition from step a) creating a co-feed composition;
- c) subjecting the furanyl containing oligomerisation composition from step a) or the co-feed composition from step b) to a hydrodeoxygenation treatment in a hydrodeoxygenation unit containing a molybdenum and/or tungsten catalyst, optionally a promoted molybdenum and/or tungsten catalyst, optionally a sulfided molybdenum and/or tungsten catalyst, resulting in a fuel composition;
- where said fuel composition contains at least 55 wt. % of both mono- and di-naphthenes and aromatics in a part of the fuel composition resulting from the hydrodeoxygenation treatment of the furanyl containing oligomerisation composition.
