Abstract:
A method to selectively remove metal compounds and sulfur from a petroleum feedstock is provided. The method comprising the steps of feeding a pre-heated water stream and a pre-heated petroleum feedstock to a mixing zone, mixing the pre-heated water stream and the pre-heated petroleum feedstock to form a mixed stream, introducing the mixed stream to a first supercritical water reactor to produce an upgraded stream, combining the upgraded stream and a make-up water stream in a make-up mixing zone to produce a diluted stream, wherein the make-up water stream increases the ratio of water to oil in the diluted stream as compared to the upgraded stream, and introducing the diluted stream to a second supercritical water reactor to produce a product effluent stream. The method can include mixing a carbon with the make-up water stream.

Claim (Index 1):
A system to selectively remove metal compounds and sulfur from a petroleum feedstock, the system comprising:\n a mixing zone, the mixing zone configured to mix a pre-heated water stream and a pre-heated petroleum feedstock to form a mixed stream, wherein the pre-heated water stream is at a temperature above the critical temperature of water and at a pressure above the critical pressure of water, wherein the pre-heated petroleum feedstock is at a temperature of less than 150\u00b0 C. and at a pressure above the critical pressure of water, wherein the pre-heated petroleum feedstock comprises a petroleum feedstock; a first supercritical water reactor fluidly connected to the mixing zone, the first supercritical water reactor configured to allow conversion reactions to occur to produce an upgraded stream, the first supercritical water reactor at a pressure above the critical pressure of water and at a temperature above the critical temperature of water, the first supercritical water reactor in the absence of externally provided hydrogen; a carbon dispersal zone, the carbon dispersal zone configured to mix carbon with a make-up water stream to produce a carbon dispersed water stream, wherein the carbon comprises a carbon material, wherein the carbon is present in a range of between 0.05 wt % of the petroleum feedstock and 1.0 wt % of the petroleum feedstock, wherein the carbon dispersed water stream is at a temperature above the critical temperature of water and a pressure above the critical pressure of water, wherein the carbon dispersal zone is in the absence of a fixed bed, such that the carbon is dispersed in the carbon dispersed water stream; a make-up mixing zone fluidly connected to the first supercritical water reactor and the carbon dispersal zone, the make-up mixing zone configured to combine the upgraded stream and the carbon dispersed water stream to produce a diluted carbon dispersed stream, wherein the carbon dispersed water stream is above the critical temperature of water and above the critical pressure of water, wherein the carbon dispersed water stream increases a volumetric flow rate ratio of water to oil in the diluted carbon dispersed stream as compared to the upgraded stream, wherein the carbon is dispersed in the diluted carbon dispersed stream, wherein the carbon is operable to trap metals present in the upgraded stream; and a second supercritical water reactor fluidly connected to the make-up mixing zone, the second supercritical reactor configured to allow conversion reactions to occur to produce a carbon dispersed effluent stream, wherein the second supercritical water reactor is at a pressure lower than the pressure in the first supercritical water reactor, wherein a temperature in the second supercritical water reactor is at least the same as the temperature in the first supercritical water reactor.
