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.

First claim

The invention claimed is:

1. 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.

2. The method according to claim 1 , where step b is mandatory.

3. The method according to claim 1 , where the fuel composition is a middle distillate fuel composition.

4. The method according to claim 1 , where the fuel composition is a drop-in fuel composition.

5. The method according to claim 1 , where the one or more material components containing fatty acids or fatty acid derivatives are selected from the group consisting of plant oil/fats, crude tall oil, tall oil fatty acids, vegetable oil/fats, animal oil/fats, fish oil/fats, algae oil/fats, oil/fats from microbial processes, genetically manipulated algae oil/fats, genetically manipulated oil/fats from microbial processes, genetically manipulated vegetable oil/fats, recyclable waste, recyclable residue, and a combination thereof.

6. The method according to claim 1 , where the oligomerisation of 2-methylfuran (2-MF) in step a) results in a furanyl containing oligomerisation composition comprising:
at least 80 wt. % oligomers selected from the group consisting of trimers, tetramers and pentamers of 2-MF comprising from 2 to 4 furanyl moieties.

7. The method according to claim 1 , where more than 60 wt % of the fuel composition has a boiling point range of 150-400° C.

8. The method according to claim 1 , where no isomerisation reactions are conducted to the fuel composition.

9. The method according to claim 1 , where the acidic catalyst in step a) is a polystyrene-co-divinylbenzene sulfonic acid resin catalyst, or any acid ion exchange resin catalyst.

10. The method according to claim 1 , comprising:
promoting the molybdenum and/or tungsten catalyst in step c) with nickel or cobalt.

11. The method according to claim 10 , where the promoted molybdenum and/or tungsten catalyst in step c) is a sulfided NiMo-catalyst.

12. The method according to claim 1 , comprising:
performing step c) under reaction conditions with a temperature between 200-400° C. and between 20 to 150 bar.
