Abstract: A process for converting hydrogen sulfide which is contained in a gaseous feed stream to elemental sulfur and hydrogen. In accordance with the process, a gaseous feed stream containing hydrogen sulfide is contacted with a polar organic solvent having a quinone and a complexing agent dissolved therein. The complexing agent must have a pKb value of less than about 13.0. Reaction of the hydrogen sulfide in the gaseous feed stream with quinone results in an increased conversion of quinone to hydroquinone at low reactor temperatures and H2S partial pressures and in increased sulfur recovery. In addition, the presence of a complexing agent increases hydrogen production selectivity in the dehydrogenation of hydroquinone to quinone and hydrogen.

Abstract: A process for removing sulfur from a hydrocarbon employs a solid membrane (20). A feed stream is provided containing a feed liquid hydrocarbon and a feed sulfur species and a sweep stream is provided containing a sweep liquid hydrocarbon. A relatively large quantity of the feed stream is conveyed past one side of the solid membrane (20), while a relatively small quantity of the sweep stream is conveyed past the opposite side of the solid membrane (20). The feed sulfur species is transported in a permeate from the feed stream through the solid membrane to the sweep stream. As a result, the feed stream is converted to a relatively large quantity of a substantially sulfur-free reject stream containing a primary hydrocarbon product, while the sweep stream combines with the permeate to produce a relatively small quantity of a sulfur-enriched stream, which is amenable to further processing.

Abstract: A process is provided for preparing a catalyst system containing a catalyst support and an associated catalyst used to catalytically dehydrogenate a hydroquinone. In accordance with the process, the catalyst support is pretreated by selecting a porous alumina of silica catalyst support and contacting it with an aqueous solution of an alkali metal salt, alkaline earth metal salt, or rare earth metal salt to produce the corresponding metal oxide on the surface of the support in a quantity sufficient to reduce the acidity thereof. The metal oxide-treated support is then contacted with a metal catalyst to produce a catalyst system having enhanced utility in the selective conversion of a hydroquinone to its corresponding quinone and hydrogen gas.

Abstract: A process for converting organic sulfur compounds contained in liquid hydrocarbons to elemental sulfur. The liquid hydrocarbons are solubilized in an organic solvent and reacted in the presence of a biocatalyst and hydrogen. The organic solvent is a nucleophilic solvent having a pK a greater than about 2, an electrophilic solvent having a pK a more negative than about -2, or mixtures thereof. The biocatalyst may be supported on a Lewis acid. Elemental sulfur is removed from the liquid hydrocarbons. Liquid hydrocarbons treated in accordance with this process have significantly reduced concentrations of organic sulfur compounds and thus reduced viscosity.

Abstract: The invention relates to a process for converting hydrogen sulfide to sulfur and hydrogen. The hydrogen sulfide gas is contacted with a quinone in an aqueous solvent containing a sulfur complexing agent to yield sulfur and the corresponding hydroquinone. The hydroquinone is converted back to quinone and hydrogen. The quinone is recycled and the hydrogen gas and sulfur is collected. The invention also discloses a range of ratios of complexing agent to quinone which produces an unexpected yield for the disclosed reaction.

Abstract: A process for catalytically dehydrogenating an anthrahydroquinone to form anthraquinone and a hydrogen product. A catalyst which is a metal, a metal compound, or a metal or metal compound dispersed on a support or is a liquid is selected to have an electronegativity greater than about 2.30 so as to result in the substantially complete conversion of anthrahydroquinone to anthraquinone and hydrogen and thereby essentially eliminate formation of unwanted hydrogenolysis by-products, such as anthrones and/or anthranols.

Abstract: A process for converting hydrogen sulfide which is contained in a gaseous feed stream to elemental sulfur and hydrogen. The process comprises contacting said gaseous feed stream with a polar organic solvent having an anthraquinone, and optionally a complexing agent, dissolved therein, reacting the hydrogen sulfide gas and anthraquinone to produce sulfur and an anthrahydroquinone in the solvent, and catalytically dehydrogenating the anthrahydroquinone to anthraquinone and hydrogen. In accordance with the present invention, a relatively small quantity of water is added to a polar organic solvent thereby increasing the elemental sulfur which is precipitated and thus recovered. The addition of water prior to or during sulfur production also increases hydrogen product selectivity in the subsequent dehydrogenation of anthrahydroquinone.

Abstract: Plugging in fluid passageways of a subterranean hydrocarbon-bearing formation or associated production wells caused by the accumulation of insoluble salt precipitates therein which results from an in situ interaction between precipitate precursor ions in an injection water and resident ions already occurring in the formation is prevented by removing the precursor ions from the injection water by a reverse osmosis membrane before injecting the water into the formation.

Abstract: A process for removing liquid sulfur from a reaction mixture during a gas treating process, especially a process for removing hydrogen sulfide from a gaseous stream. Sulfur which is formed during the process is removed from a reaction mixture by first concentrating the sulfur in a small portion of the reaction mixture and then heating this portion to a temperature which is sufficient to melt the sulfur. The molten sulfur is removed from the reaction mixture and washed with a suitable solvent to remove any remaining reaction mixture.
