Abstract

A process for converting one or more C3-C12 oxygenates comprising oxygenates comprising: contacting a feed, which feed comprises one or more C3-C12 oxygenates, with hydrogen at a hydrogen partial pressure of more than 1.0 Mega Pascal in the presence of a sulphided carbon-carbon coupling catalyst; wherein the carbon-carbon coupling catalyst comprises equal to or more than 60 wt % of a zeolite and in the range from equal to or more than 0.1 wt % to equal to or less than 10 wt % of a hydrogenation metal, based on the total weight of the carbon-carbon coupling catalyst; and wherein the zeolite comprises 10-membered and/or 12-membered ring channels and a Silica to Alumina molar Ratio (SAR) in the range from equal to or more than 10 to equal to or less than 300.

First claim

That which is claimed is:

1. A process for converting one or more C3-C12 oxygenates comprising:
contacting a feed, which feed comprises one or more C3-C12 oxygenates, with hydrogen at a hydrogen partial pressure of more than 1.0 MegaPascal in the presence of a sulphided carbon-carbon coupling catalyst;
wherein the carbon-carbon coupling catalyst comprises at least 60 wt % of a zeolite and in the range from at least 0.1 wt % to at most 10 wt % of a hydrogenation metal, based on the total weight of the carbon-carbon coupling catalyst; and wherein the zeolite comprises 10-membered and/or 12-membered ring channels and a Silica to Alumina molar Ratio (SAR) in the range from 10 to 300.

2. The process according to claim 1 wherein the carbon-carbon coupling catalyst comprises in the range from at least 0.5 wt % to at most 5 wt % of a hydrogenation metal, based on the total weight of the carbon-carbon coupling catalyst.

3. The process according to claim 1 wherein the feed is contacted with the sulphided carbon-carbon coupling catalyst at a temperature in the range from at least 250° C. to at most 450° C.

4. The process according to claim 1 wherein the feed comprises sulphur in a concentration in the range from at least 150 ppmw to at most 2000 ppmw.

5. The process according to claim 1 wherein the feed comprises nitrogen in a concentration in the range from at least 300 ppmw to at most 5000 ppmw.

6. The process according to claim 1 wherein a conversion product is produced, which conversion product is subsequently contacted with a hydrotreating catalyst and/or a hydroisomerization catalyst.

7. The process according to claim 6 wherein the sulphided carbon-carbon coupling catalyst and the hydrotreating catalyst and/or hydroisomerization catalyst are combined in a stacked bed configuration, where the sulphided carbon-carbon coupling catalyst is located upstream of the hydrotreating catalyst and/or hydroisomerization catalyst.

8. The process according to claim 6 wherein the weight ratio of sulphided carbon-carbon coupling catalyst to hydrotreating catalyst and/or a hydroisomerization catalyst is from 1:1 to 4:1.

9. The process according to claim 1 wherein further a C1-C3 hydrocarbon product is produced, which C1-C3 hydrocarbon product is converted in a steam methane reformer to produce hydrogen.

10. The process according to claim 9 wherein the produced hydrogen is recycled to the process.

11. The process according to claim 1 wherein a middle distillate boiling product is produced.
