  • Publication number: 20110139684
    Abstract: A sulfur reduction catalyst useful to reduce the levels of sulfur in a cracked gasoline product comprises a metal vanadate compound. The metal vanadate compound can be supported on a molecular sieve such as a zeolite in which the metal vanadate compound is primarily located on the exterior surface of the pore structure of the zeolite and on the surface of any matrix material used to bind or support the zeolite.

  • Publication number: 20080053902
    Abstract: Methods are provided for separation of substances using non-crystalline, amorphous inorganic oxides having mesoporosity or combined meso- and microporosity. The amorphous inorganic oxide may have a separating agent, such as a chemical functional group, bonded or attached to the surfaces within the pores. The amorphous inorganic material is exposed to a fluid containing two or more materials to be separated. At least one material contained in the fluid is preferentially retained by the amorphous inorganic oxide either on the surface of the inorganic oxide within the pores or by interaction with a separating agent group attached to the pore surfaces.
