Particulate sorbent compositions comprising a mixture of zinc oxide, silica, alumina and a substantially reduced valence cobalt are provided for the desulfurization of a feedstream of cracked-gasoline or diesel fuels in a desulfurization zone by a process which comprises the contacting of such feedstreams in a desulfurization zone followed by separation of the resulting low sulfur-containing stream and sulfurized-sorbent and thereafter regenerating and activating the separated sorbent before recycle of same to the desulfurization zone.

Methods and systems for contacting of a crude feed with one or more catalysts to produce a total product that includes a crude product are described. The crude product is a liquid mixture at 25° C. and 0.101 MPa. The crude product has an MCR content of at most 90% of the MCR content of the crude feed. One or more other properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.

The purpose of the invention is to provide a heavy oil reforming method which reforms a heavy oil to give a fuel suitable for a gas turbine, eliminates sulfur and vanadium, i.e., harmful components, from a heavy oil, and enables almost all the hydrocarbons in the heavy oil to be used in gas turbine combustion; an apparatus therefor; and a gas turbine power generation system using the reformed heavy oil as fuel. This method comprises reacting a heavy oil with supercritical water and then with a scavenger for sulfur and vanadium to eliminate sulfur and vanadium from the heavy oil. The apparatus for reforming a heavy oil is equipped with a reactor for reacting a heavy oil with supercritical water, a scavenging apparatus filled with a scavenger for scavenging sulfur and vanadium in the heavy oil, and a connecting pipe for connecting the reactor and the scavenging apparatus. The gas turbine power generation system has a burner for burning a heavy oil reformed with the reforming apparatus and a gas turbine driven by a combustion gas generated by the burner.

Contact of a crude feed with one or more catalysts produces a total product that includes a crude product. The crude feed may include at least 0.1 grams of vacuum gas oil per gram of crude feed. The crude product is a liquid mixture at 25° C. and 0.101 MPa. The crude product may have a vacuum gas oil content of about 30% to about 70% of the vacuum gas oil content of the crude feed. One or more other properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.

The reforming of heavy oil with supercritical water or subcritical water is accomplished by mixing together supercriticai water, heavy oil, and oxidizing agent, thereby oxidizing vanadium in heavy oil with the oxidizing agent at the time of treatment with supercritical water and separate vanadium oxide. The separated vanadium oxide is removed by the scavenger after treatment with supercritical water. In this way it is possible to solve the long-standing problem with corrosion of turbine blades by vanadium which arises when heavy oil is used as gas turbine fuel.

The present invention is a method for the adsorption of sulfur-containing compounds from a hydrocarbon feedstream, and in particular, an olefin feedstream. The method comprises contacting the sulfur-containing compound with a copper oxide / zinc oxide / aluminum oxide catalyst optionally promoted with a metal.

Contact of a crude feed with one or more catalysts produces a total product that includes a crude product. The crude feed has a total content of alkali metal, and alkaline-earth metal, in metal salts of organic acids of at least 0.00001 grams per gram of crude feed. The one or more catalysts may include a first and a second catalyst. The crude product is a liquid mixture at 25° C. and 0.101 MPa and has a total content of alkali metal, and alkaline-earth metal, in metal salts of organic acids of at most 90% of the total content of alkali metal, and alkaline-earth metal, in metal salts of organic acids of the crude feed. One or more other properties of the crude product may be changed by at least 10% relative to the respective properties of the crude feed.

A process for the upgrading of raw hydrocarbon streams rich in heteroatomic polar compounds and / or unsaturated moieties involving the extractive oxidation of sulfur, nitrogen, conjugated dienes and other unsaturated compounds from said streams, the said process comprising treating said streams with a peroxide solution / organic acid couple and an iron oxide catalyst which is a limonite ore, under an acidic pH, atmospheric pressure and ambient or higher temperature. As a result of the reaction, the oxidized heteroatomic compounds, having strong affinity for the aqueous slurry phase, are extracted into said aqueous phase, while the oxidized hydrocarbon is separated from catalyst by decanting, neutralizing, water washing and drying, the resulting end product being a hydrocarbon stream from which have been removed 90% or more of total nitrogen compounds and basic nitrogen up to 99.7%, both calculated as mass contents.
