Abstract
A process for upgrading a hydrocarbon-based composition includes combining a heated water stream and a pressurized, heated hydrocarbon-based composition in a mixing device to create a combined feed stream. The combined feed stream is introduced into a supercritical water reactor operating at a temperature greater than a critical temperature of water and a pressure greater than a critical pressure of water. The combined feed stream is at least partially converted to an upgraded product. At least one catalyst lobular structure is present in the supercritical water reactor.

A process for upgrading a hydrocarbon-based composition comprising:
- combining a heated water 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 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,
- wherein at least one catalyst lobular structure comprising a non-porous metal is present in the supercritical water reactor.
A process for upgrading a hydrocarbon-based composition comprising:
- combining a heated water 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 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, wherein
- at least one catalyst lobular structure is present in the supercritical water reactor,
- the at least one catalyst lobular structure comprises a metal selected from the group consisting of Fe, Ni, Pt, Mo, Cr, Zn and combinations thereof, and
- an additive selected from the group consisting of aluminum, silicon, boron, gallium, indium, bismuth, and combinations thereof.
A process for upgrading a hydrocarbon-based composition comprising:
- combining a heated water 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 reactor operating at a temperature greater than a critical temperature of water and a pressure greater than a critical pressure of water;
- at least partially converting the combined feed stream to an upgraded product;
- and
- passing the upgraded product out of the supercritical water 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, wherein
- the gas fraction comprises hydrogen, and the hydrogen is recycled and mixed to be part of the combined feed stream, and
- at least one catalyst lobular structure is present in the supercritical water reactor.
