Abstract

Systems and methods are provided for processing a feed derived from a renewable source to form oligomerized compounds corresponding to waxes, ketone waxes, and/or lubricant boiling range compounds. The oligomerized compounds derived from the renewable source can have various novel properties relative to waxes and/or lubricant boiling range compounds derived from mineral sources or derived from renewable sources in a conventional manner. The oligomerized compounds can be derived from a renewable source including fatty acids and/or fatty acid derivatives, such as glycerides (including triglycerides) and fatty amides. Optionally but preferably, at least a portion of the fatty acids and/or fatty acid derivatives can include olefinic bonds.

First claim

The invention claimed is:

1. A ketone wax composition comprising at least about 80 wt % of compounds having a carbon chain length of 27 carbons to 39 carbons, at least about 30 wt % of the compounds having a carbon chain length of 27 carbons to 39 carbons comprising oxygenates, at least a portion of the oxygenates comprising ketones, the ketone wax composition comprising a kinematic viscosity at 100° C. of about 3.0 cSt to about 7.5 cSt and a melting point of at least about 78° C., the compounds having a carbon chain length of 27 carbons to 39 carbons comprising at least about 20 wt % of compounds having a first carbon chain length, at least about 20 wt % of compounds having a second carbon chain length, and at least about 20 wt % of compounds having a third carbon chain length, wherein about 20 wt % to about 90 wt % of the compounds having a chain length of 27 carbons to 39 carbons comprise olefins.

2. The ketone wax composition of claim 1 , wherein the largest difference in carbon chain length between any two of the first carbon chain length, the second carbon chain length, and the third carbon chain length comprises 6 carbons or less.

3. The ketone wax composition of claim 1 , wherein the ketone wax composition comprises a kinematic viscosity at 100° C. of about 3.0 cSt to about 6.5 cSt.

4. The ketone wax composition of claim 1 , wherein the ketone wax composition comprises a kinematic viscosity at 100° C. of about 6.0 cSt to about 7.5 cSt and a melting point of at least about 83° C.

5. The ketone wax composition of claim 1 , wherein the ketone wax composition comprises at least about 90 wt % of compounds having a carbon chain length of 27 carbons to 39 carbons.

6. The ketone wax composition of claim 1 , wherein at least about 50 wt % of the compounds having a chain length of 27 carbons to 39 carbons comprise oxygenates.

7. The ketone wax composition of claim 1 , wherein at least about 50 wt % of the compounds having a chain length of 27 carbons to 39 carbons comprise ketones.

8. The ketone wax composition of claim 1 , wherein at least about 80 wt % of the compounds having 27 carbons to 39 carbons have chain lengths that differ by about 6 carbons or less.
