Abstract: A process for removing sulfur compounds from a liquid composition immiscible with water, comprising at least partially oxidizing the sulfur compounds by contacting a liquid composition comprising at least one sulfur compound with an aqueous oxidizing solution comprising at least one oxidant in the presence of at least one polyoxometalate and amphiphilic solid particles.

Abstract: A continuous process for producing hydrogen peroxide by an anthraquinone process, comprising the steps of: (i) hydrogenating an organic working solution containing one or more anthraquinone derivatives in the presence of a heterogeneous catalyst to form a hydrogenated working solution; (ii) oxidizing the hydrogenated working solution by introducing an oxygen-containing oxidizing gas at an overpressure into an oxidation reactor, and contacting the oxidizing gas with the hydrogenated working solution to form an oxidized working solution, whereby hydrogen peroxide is formed; (iii) withdrawing an oxidation off gas from the oxidation reactor; (iv) recovering the formed hydrogen peroxide from the oxidized working solution; (v) subjecting the oxidation off gas withdrawn from said oxidation reactor, which has an excess pressure over atmospheric pressure, to a demisting treatment to obtain a demisted oxidation off gas; and (vi) feeding the demisted oxidation off gas as propellant gas into a gas ejector to produce a vacuum.

Abstract: The present invention therefore pertains to a process for desulfurizing a sulfur compound-containing liquid fossil fuel. By continuously adding a solution comprising an oxidant to the sulfur compound-containing liquid fossil fuel, it is possible to improve oxidant utilization and achieve higher sulfur removal rate.
