Abstract

A process for upgrading a hydrocarbon-based composition that includes combining a supercritical water stream, a hydrogen stream, and a pressurized, heated hydrocarbon-based composition in a mixing device to create a combined feed stream. The process further includes introducing the combined feed stream into a supercritical water hydrogenation reactor operating at a temperature greater than a critical temperature of water and a pressure greater than a critical pressure of water, and at least partially converting the combined feed stream to an upgraded product.

First claim

What is claimed is:

1. A process for upgrading a hydrocarbon-based composition comprising:
combining a heated water stream, a hydrogen stream, and a pressurized, heated hydrocarbon-based composition in a mixing device to create a combined feed stream;
introducing the combined feed stream into a supercritical water hydrogenation reactor operating at a temperature greater than a critical temperature of water and a pressure greater than a critical pressure of water; and
at least partially converting the combined feed stream to an upgraded product.

2. The process of claim 1 , further comprising passing the upgraded product out of the supercritical water hydrogenation reactor to a gas/oil/water separator and separating the upgraded product in the gas/oil/water separator to produce a gas fraction, a liquid oil fraction, and a water fraction.

3. The process of claim 1 , further comprising passing the upgraded product to a cooling device to form a cooled upgraded product.

4. The process of claim 3 , further comprising passing the cooled upgraded product to a depressurizing device.

5. The process of claim 4 , further comprising depressurizing the cooled upgraded product to less than 1 MPa.

6. The process of claim 1 , wherein the pressurized, heated hydrocarbon-based composition has a temperature from 100° C. to 370° C.

7. The process of claim 1 , wherein the supercritical water hydrogenation reactor has a temperature of greater than 375° C. and less than 600° C. and a pressure greater than 22.1 MPa and less than 75 MPa.

8. The process of claim 1 , wherein the supercritical water hydrogenation reactor has a temperature of greater than 390° C. and less than 470° C. and a pressure greater than 24 MPa and less than 30 MPa.

9. The process of claim 1 , wherein the supercritical water hydrogenation reactor has a residence time of from 1 to 30 minutes.

10. The process of claim 1 , wherein the supercritical water hydrogenation reactor has a residence time of from 2 to 15 minutes.
