    摘要: Titanovanadosilicalites 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. Vanadium incorporation at levels of Si:V in the range 100-2500 effectively changes the characteristics of the titanosilicalite into which it is incorporated to give near quantitative conversion of propylene at selectivities greater than 90%.

    摘要: A new family of crystalline titanostannosilicate molecular sieves have been synthesized. These molecular sieves have a microporous three-dimensional framework of TiO.sub.2, SnO.sub.2 and SiO.sub.2 tetrahedral oxide units and are represented by the empirical formula:(Ti.sub.x Sn.sub.y Si.sub.z)O.sub.2where "X", "y" and "z" are the mole fractions of Ti, Sn and Si respectively. These molecular sieves are active catalysts for the epoxidation of olefins by peroxides such as hydrogen peroxide.

    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.

    摘要: The service life and deactivation rate of a benzene saturation catalyst is improved through use of a new sulfur guard bed containing a chloride additive. This sulfur guard bed, which contains supported CuO material having an increased resistance to reduction, shows such improvement. Thus, the danger of run-away reduction followed by a massive release of water and deactivation of an isomerization catalyst is practically eliminated. The fact that the guard bed material preserves the active metal phase-copper in an active (oxide) form is an important advantage leading to very low sulfur content in the product stream. The sulfur capacity per unit weight of sorbent is also significantly increased, making this sorbent a superior cost effective sulfur guard product. The guard bed is effective in treating mixed phase feed streams.

    摘要: The service life and deactivation rate of a reforming catalyst is improved through use of a new sulfur guard bed containing a chloride additive. This sulfur guard bed, which contains supported CuO material having an increased resistance to reduction, shows such improvement. Thus, the danger of run-away reduction followed by a massive release of water causing process upsets in a catalytic reforming process is practically eliminated. The fact that the guard bed material preserves the active metal phase—copper in an active (oxide) form is an important advantage leading to very low sulfur content in the product stream. The sulfur capacity per unit weight of sorbent is also significantly increased, making this sorbent a superior cost effective sulfur guard product.
