    Abstract: A process for the preparation of a ceramic foam supporting one or more catalytically active components or precursors thereof, which component is active in a form other than an inorganic oxide, the process comprising impregnation of the foam with an impregnating phase comprising the catalytically active component or a precursor thereof and drying, wherein the impregnating phase has a viscosity greater than 1 cps, wherein drying is performed without substantial prior draining of impregnating phase from the ceramic foam, and wherein the catalytically active component or precursor thereof is present throughout the process in one or more forms other than the inorganic oxide thereof. The ceramic foams prepared by this process find use in catalytic conversion processes, in particular the catalytic partial oxidation of a hydrocarbon feed.

    Abstract: The present invention relates to high oxygen ion conducting/oxygen storage (OIC/OS) materials, a catalyst employing the OIC/OS materials, and a method for converting hydrocarbons, carbon monoxide and nitrogen oxides using the catalyst. The OIC/OS materials have significantly higher oxygen storage capacity than that predicted based on Ce content due to the unexpected high and facile redox activity of the added niobium. These materials are further characterized by having a tetragonal crystalline structure under oxidizing conditions (in air) up to about 1,200° C. and a cubic crystalline structure in reducing conditions (5% hydrogen) up to about 1,000° C. for 24 hours. These materials comprise, based upon 100 mole % of the metal component in the material, up to about 95 mole % zirconium, up to about 50 mole % cerium, about 0.5 to about 15 mole % rare earth metal(s), alkaline earth metal(s) or a combination thereof, and about 0.5 to about 15 mole % niobium.

    Abstract: The invention is a polymerization catalyst system derived from tethered, heteroatom-bridged monocyclopentadienyl transition metal compound precursor from Group 4 of the Periodic Table of the Elements. The catalyst system comprises an activated, tethered pair of Group 4 transition metal compounds having a bidentate ancillary ligand system consisting of one cyclopentadienyl group bound to the transition metal and a Group 15 or Group 16 atom covalently bound to the transition metal and linked to the cyclopentadienyl group through a bridging group containing a Group 14-15 element. The ligand systems of each transition metal compound are tethered by at least one tethering group comprising a Group 13-16 element connected at both ends to either the Group 15 or Group 16 atom or the Groups 14-15 bridging group element. The catalyst system can be employed to polymerize olefins to produce a high molecular weight polymer.

    Abstract: A hydrocracking catalyst is provided that includes a crystalline molecular sieve material component having a faujasite structure and an alpha acidity of less than 1, preferably 0.3 or less, and a dispersed Group VIII noble metal component. The extremely low acidity allows selective hydrocracking of the aromatic and naphthenic species in a feedstock, while limiting the cracking of paraffins. The catalyst produces improved yields of products, such as diesel fuel, at high conversion rates and with high cetane values.
