Zusammenfassung:To provide a system including process for upgrading a petroleum-based composition.SOLUTION: The present invention comprises a step for forming a combined feed stream by combining a supercritical water stream with a petroleum-based composition; a step for introducing the combined feed stream into an upgrading reactor system comprising a supercritical upgrading reactor comprising a first catalyst layer, which is a heterogeneous porous metal containing catalyst having a first void volume ratio and a second catalyst layer, which is a heterogeneous porous metal containing catalyst having a second void volume ratio where the second void volume ratio is less than the first void volume ratio; a step for flowing light hydrocarbons in the combined feed stream at least partially through the first catalyst layer and the second catalyst layer while sifting and passing heavy hydrocarbons in the combined stream in a void of the catalyst layer; a step for partially converting sifted heavy hydrocarbons to light hydrocarbons; a step for passing an upgraded product comprising light hydrocarbons and converted light hydrocarbons out of the supercritical upgrading reactor.SELECTED DRAWING: None 【課題】石油系組成物を改良するためのプロセス等を提供する。【解決手段】超臨界水ストリームを石油系組成物と組み合わせて供給物ストリームを形成するステップと、第1の触媒層(第1の空隙体積比を有する不均一多孔質金属含有触媒)及び第2の触媒層(第2の空隙体積比を有する不均一多孔質金属含有触媒)を備え、第2の空隙体積比は、第1の空隙体積比より小さい超臨界改良反応器を備える改良反応器システムに供給物ストリームを導入するステップと、供給物ストリーム中の軽質炭化水素を、少なくとも部分的に第1の触媒層及び第2の触媒層を通って流動させ、供給物ストリーム中の重質炭化水素は触媒層の空隙内で篩い分けされる通過させるステップと、篩い分けされた重質炭化水素を部分的に軽質炭化水素に変換するステップと、軽質炭化水素及び変換された軽質炭化水素を含む改良された生成物を超臨界改良反応器の外に通過させるステップとを含む。【選択図】なし
