    • A process for removing metals, sulfur and nitrogen in the upgrading of hydrocarbons comprising: mixing hydrocarbons containing metals, sulfur and nitrogen with a fluid comprising water that has been heated to a temperature higher than its critical temperature in a mixing zone to form a mixture; passing the mixture to a reaction zone; reacting the mixture in the reaction zone under supercritical water conditions in the absence of externally added hydrogen for a residence time sufficient to allow upgrading reactions to occur while maintaining an effective amount of metals, derived from the hydrocarbon undergoing upgrading, in the reaction zone to catalyze the upgrading reactions; and recovering upgraded hydrocarbons having a lower concentration of metals, sulfur and nitrogen than the hydrocarbons before reaction is disclosed.
    • 一种用于在烃的提质中除去金属,硫和氮的方法,包括:将含有金属,硫和氮的烃与包含水的流体混合,所述流体在混合区中被加热到高于其临界温度的温度以形成混合物; 将混合物通入反应区; 在超临界水条件下,在不存在外加氢气的情况下使混合物在反应区内反应停留时间,足以使得在反应区中维持有效量的衍生自正在升级的烃的催化剂 升级反应; 并且公开了在反应之前回收具有比烃低的金属,硫和氮浓度较低的升级烃。

    • A method for reducing mercaptan concentration in a liquid hydrocarbon, comprising: contacting a mercaptan-rich liquid hydrocarbon having a first concentration of mercaptan sulfur with a composition comprising an oxidizing agent and water wherein the molar ratio of the oxidizing agent to mercaptan sulfur in the mercaptan-rich liquid hydrocarbon is from 3:1 to 10:1; and separating the water from the liquid hydrocarbon to yield a mercaptan-depleted liquid hydrocarbon having a second concentration of mercaptan sulfur, the second concentration being less than the first concentration; wherein a major amount of mercaptan compounds in the mercaptan-rich liquid hydrocarbon are converted to at least one sulfur oxoacid or salt thereof, having the formula: [RSOx]nY wherein R is a hydrocarbyl group; x is an integer from 1 to 3; n is 1 or 2; and Y is hydrogen, an alkaline metal, or alkaline earth metal.
