    摘要： Catalysts for oxidative sulfur removal and methods of making and using thereof are described herein. The catalysts contain one or more reactive metal salts dispersed on one or more substrates. Suitable reactive metal salts include those salts containing multivariable metals having variable valence or oxidation states and having catalytic activity with sulfur compounds present in gaseous fuel streams. In some embodiments, the catalyst contains one or more compounds that function as an oxygen sponge under the reaction conditions for oxidative sulfur removal. The catalysts can be used to oxidatively remove sulfur-containing compounds from fuel streams, particularly gaseous fuel streams having high sulfur content. Due to the reduced catalyst cost, anticipated long catalyst life and reduced adsorbent consumption, the catalysts described herein are expected to provide a 20-60% reduction in annual desulfurization cost for biogas with sulfur contents ranges from 1000-5000 ppmv compared with the best adsorbent approach.

    摘要： HYDROGEN PEROXIDE IS SOLUBILIZED IN A MICELLAR DISPERSION, I.E. STABLE SYSTEMS CONTAINING HYDROCARBON, AQUEOUS MEDIUM, AND SURFACTANT. THE HYDROGEN PEROXIDE-CONTAINING MICELLAR DISPERSION IS THEN ADMIXED WITH ANY LIQUID MEDIA IN WHICH HYDROGEN PEROXIDE IS TO BE USED AS A REACTANT OR CATALYST TO EFFECT INTIMATE CONTACT AND DISPERSION OF THE HYDROGEN PEROXIDE WITHIN THE LIQUID MEDIA. IN THIS MANNER SOUR HYDROCARBON STREAMS ARE SWEETENED, FOR INSTANCE.
