Abstract:
Supercritical upgrading reactors and reactor systems for upgrading a petroleum-based compositions comprising one or more catalyst layers and, in some embodiments, one or more purging fluid inlets, where one or more catalyst layers at least partially sift and convert heavy hydrocarbon fractions to light hydrocarbon fractions to produce an upgraded supercritical reactor product. In some embodiments, upgrading reactor systems comprise one or more supercritical upgrading reactors and one or more supercritical standby reactors alternating functions such that a supercritical upgrading reactor is converted to a supercritical standby reactor and the supercritical standby reactor is converted to a supercritical upgrading reactor, where the supercritical upgrading reactor upgrades a combined feed stream while a supercritical standby reactor delivers a cleaning fluid into the supercritical standby reactor.

Claim (Index 7):
A process for upgrading a petroleum-based composition comprising:\n combining a supercritical water stream with a pressurized, heated petroleum-based composition in a mixing device to create a combined feed stream, introducing the combined feed stream into an upgrading reactor system comprising at least one supercritical upgrading reactor operating at a temperature greater than a critical temperature of water and a pressure greater than a critical pressure of water,\n where the supercritical upgrading reactor comprises a first catalyst layer and a second catalyst layer, the second catalyst layer disposed vertically below the first catalyst layer in the supercritical upgrading reactor \n where the first catalyst layer comprises a catalyst having a first void volume ratio and the second catalyst layer comprises a catalyst having a second void volume ratio, and \n where the second void volume ratio is less than the first void volume ratio, \n passing the combined feed stream through the first catalyst layer and the second catalyst layer, where light hydrocarbons in the combined feed stream at least partially flow through the first catalyst layer and the second catalyst layer while heavy hydrocarbons in the combined feed stream are at least partially sifted in voids of the first catalyst layer, voids of the second catalyst layer, or both; at least partially converting the sifted heavy hydrocarbons to light hydrocarbons in the first catalyst layer or the second catalyst layer in the presence of the supercritical water; and passing upgraded product comprising light hydrocarbons and the converted light hydrocarbons out of the supercritical upgrading reactor.
