    摘要: Applicants have developed a novel catalyst composition comprising a crystalline metal oxide having the empirical formula: AvBt+wNixD(Gu−)yOz, where A is an alkali metal (e.g. Na), B is a basic metal (e.g. Ca), D is a framework component (e.g. P), and G is an anionic species (e.g. OH−). Nickel may be present in the framework of the crystalline metal oxide, dispersed thereon, or both. Preferably, the metal oxide component has an apatite or hydroxyapatite crystal structure. These crystalline metal oxide components have been found to have improved performance in partial oxidation and light hydrocarbon (e.g. methane) reforming to produce synthesis gas. A new process for synthesizing these metal oxides is also disclosed.

    摘要: This invention relates to novel crystalline metallo manganese oxides that has the hollandite structure. The composition is represented by the formulaA.sub.y Mn.sub.8-x M.sub.x O.sub.16where A is a templating agent such as potassium, ammonium, and y varies from about 0.5 to about 2.0, M is a metal such as chromium, vanadium, gallium, antimony and x varies from about 0.01 to about 4.0. These oxides have a three-dimensional structure with manganese and the M metals forming the framework. Finally, these novel oxides are capable of catalyzing hydrocarbon conversion processes such as oxidation and oxidative dehydrogenation.

    摘要: Titanostannosilicalites molecular sieves as new compositions of matter have been found to be very selective, active catalysts in the epoxidation of olefins by peroxides. Dilute hydrogen peroxide suffices to afford high yields of the epoxide with good selectivity. The sieves described within have a unit empirical formula, on an anhydrous basis of (Ti.sub.x Sn.sub.y Si.sub.z)O.sub.2, where 0.0005

    摘要: A new family of crystalline manganese phosphate compositions has been prepared. These compositions have an extended network which network can be a one-, two-, or three-dimensional network. The composition has an empirical formula of: (A.sup.a+).sub.v (Mn.sup.b+)(M.sup.c+).sub.x P.sub.y O.sub.z where A is a templating agent such as an alkali metal, M is a metal such as Al, Fe.sup.3+ and "b" is the average manganese oxidation state and varies from greater than 3.0 to about 4.0. These compositions can be used as adsorbents and as catalysts in the oxidation of hydrocarbons.
