    摘要: This invention belongs to the technical field of inorganic chemical synthesis, relating to a modification method for titanium-silicalite zeolite (TS-1). The feature of the invention is pretreating the TS-1, after that the TS-1 is modified by the mixture of quaternary ammonium salts and inorganic base. The quaternary ammonium salts mentioned above include tetrapropylammonium fluoride, tetrapropylammonium chloride, tetrapropylammonium iodide and their mixture. The inorganic base include that LiOH, NaOH and KOH and their mixture. TS-1 after the modification is aftertreated at last. The benefit of the invention is universal capable to modify the TS-1 synthesized by any method, specially the TS-1 with low cost method, the modification can enhance the catalytic performance on both gas and liquid phase epoxidation of propylene.

    摘要: Fuel conditioning modules that condition a combustible fuel prior to combustion are provided so that fuel to be conditioned is brought into contact with a fuel conditioning insert which includes a zeolite catalyst material comprised of a mixture of zeolite particulates and rare earth metal or metal oxide particulates in a solid resin binder disposed in a housing flow through passageway such that the fuel flowing in the passageway between inlet and outlet ends of the housing contacts the fuel conditioning insert assembly. The catalytic metal is most preferably at least one selected from the group consisting of copper, aluminum, stainless steel, titanium, magnesium, chromium, barium, calcium, platinum, palladium, nickel, bronze and iron. The zeolite catalyst material may be dispersed in the form of solid chips throughout a mass of metallic elements form of a catalytic metal.

    摘要: In a process for producing hydroperoxides, an alkylaromatic compound of general formula (I): in which R1 and R2 each independently represents an alkyl group having from 1 to 4 carbon atoms, provided that R1 and R2 may be joined to form a cyclic group having from 4 to 10 carbon atoms, said cyclic group being optionally substituted, and R3 represents hydrogen, one or more alkyl groups having from 1 to 4 carbon atoms or a cyclohexyl group, with oxygen in the presence of a catalyst comprising a manganese oxide molecular sieve to produce a hydroperoxide of general formula (II): in which R1, R2 and R3 have the same meaning as in formula (I). The hydroperoxide of formula (II) may then be converted to a phenol and an aldehyde or a ketone of the general formula R1COCH2R2 (III), in which R1 and R2 have the same meaning as in formula (I). In the case where the ketone is cyclohexanone, this may then be dehydrogenated to produce further phenol.
