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： 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： 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： 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 reforming and isomerization process has been developed. A reforming feedstream is charged to a reforming zone containing a reforming catalyst and operating at reforming conditions to generate a reforming zone effluent. Hydrogen and an isomerization feedstream is charged into an isomerization zone to contact an isomerization catalyst at isomerization conditions to increase the branching of the hydrocarbons. The isomerization catalyst is a solid acid catalyst comprising a support comprising a sulfated oxide or hydroxide of at least an element of Group IVB, a first component being at least one lanthanide series element, mixtures thereof, or yttrium, and a second component being a platinum group metal or mixtures thereof. The reforming zone effluent is combined with the isomerization zone effluent to form a combined effluent stream and separated into a product stream enriched in C5 and heavier hydrocarbons and an overhead stream enriched in C4 and lighter boiling compounds.

摘要： Carbonaceous pyropolymers possessing recurring units containing at least carbon and hydrogen atoms on their surface are effective in removing from solution metal cations having a standard reduction potential to their zerovalent state of greater than -0.2 volts. Their mode of action appears to be via reduction of the metal to the zerovalent state which then is deposited on the pyropolymer surface.
