Abstract: The invention is a nitrogen oxide trap comprising a porous support of alumina; and loaded thereon materials consisting essentially of particular amounts of: (I) tungstophosphoric acid and (II) precious metal selected from platinum, palladium, rhodium and mixtures thereof. The trap is useful for trapping nitrogen oxides produced in the exhaust gas generated by an internal combustion gasoline engine during lean-burn operation of the engine. The trap releases the nitrogen oxides during decreased oxygen concentration in the exhaust gas. The desorbed NOx may be converted over the precious metal to N.sub.2 and O.sub.2 by reductants like hydrocarbons present in the exhaust gas.

Abstract: A catalyst containing an overlayer of a catalytic promoter on a porous refractory support containing an underbedded Group VIII metal-containing component. The catalyst is prepared by sequential incorporation of the Group VIII metal followed by the additional catalytic promoter component, usually a Group VIB metal, with the porous refractory oxide support. Underbedded nickel components on the catalyst are characterized by a unique Raman spectrum exhibiting Raman bands in the region of about 240 cm.sup.-1 to about 250 cm.sup.-1 and in the region of about 595 cm.sup.-1 to about 605 cm.sup.-1. The catalyst has a MoO.sub.3 /NiO weight ratio less than 6 to 1 and more than 4 weight percent of NiO. The catalyst is especially useful for simultaneous hydrodenitrogenation and hydrodesulfurization of a gas oil, particularly when the refractory oxide support has a narrow pore size distribution.

Abstract: Alkenes can be expoxidized with hydrogen peroxide using a homogeneous heavy metal catalyst, but discharge of spent reaction mixtures releases the heavy metal in the environment. The problem can be ameliorated by selecting a heterogeneous catalyst system comprising a tungsten-containing heteropolyacid supported on selected Group IIa, IIb, IVa or IVb inorganic supports or on a strong basic resin, which catalyst has either been calcined after impregnation of in the impregnation stage an alcoholic solution of the heteropolyacid is employed and by employing a nitrilo or oxygenated polar solvent reaction medium. A number of preferred heteropolyacids satisfy the empirical formula M.sub.3/n PW.sub.w MO.sub.12-w O.sub.40 in which w represents an integer of at least 1, M represents a counterion and n its basicity. Preferred supports include activated alumina, calcined at 400.degree. to 600.degree. C. and cross-linked quaternary ammonium-substituted polystyrene resins. The most preferred catalysts are made by impregnating an inorganic support with a methanol solution of the heteropolyacid to a desired loading of active material on the support and subsequently calcining the loaded support at 400.degree. to 600.degree. C. Preferred reaction media include acetonitrile and tertiary butanol.
