Abstract
A method of mixing a catalyst with a heavy oil to create a heavy oil/catalyst mixture. This is followed by combining the heavy oil/catalyst mixture with supercritical water to form light hydrocarbon products and heavy hydrocarbon products. By doing so the light hydrocarbon products can be separated into a gaseous top product, an upgraded liquid hydrocarbon product and a water phase.
