    摘要： Es wird ein Verfahren zur Oligomerisierung von Olefinen beschrieben. Um Umweltverschmutzungs- und Korrosionsprobleme zu vermeiden, wird vorgeschlagen, daß die Oligomerisierung in der Gasphase an einem festen Katalysator, der supersaure Fluorverbindungen der Elemente der III., IV. und/oder V. Hauptgruppe des Periodensystems enthält, durchgeführt wird. Das Verfahren kann beispielsweise zur Erhöhung der Olefinausbeute in Steamcrackern oder zur Gewinnung von Kraftstoffkomponenten aus FCC-Abgasen eingesetzt werden.

    摘要： A solid composition of matter selected from the group consisting of:

    (a) a component comprising: (1) an oxide of lanthanum and a component comprising: (2) at least one material selected from the group consisting of halogen ions, compounds containing halogen ions, tin and compounds containing tin; and
    (b) a component comprising: (1) at least one material selected from the group consisting of Group IA metals and compounds containing said metals, a component comprising: (2) at least one metal selected from the group consisting of lanthanum and compounds containing lanthanum and, optionally, a component comprising: (3) at least one material selected from the group consisting of halogen ions, compounds containing halogen ions, tin and compounds containing tin,

    and a method for the oxidative conversion of organic compounds to other organic compounds, particularly in the presence of a free oxygen containing gas. When the method is carried out in the presence of a free oxygen containing gas, a contact material including a Group IA metal, tin and, optionally, chloride ions has also been found to be effective.

    摘要： A novel catalyst for use in dehydrogenation of saturated hydrocarbons to unsaturated hydrocarbons and a method for its preparation is disclosed. Said catalyst comprises a composite incorporated within its spatial geometry on a percentage by weight basis, with a uniform concentration gradient, the following active elements:

    from 0.1 to 5.0% of a noble metal;
    from 0.1 to 5.0 % of a metal of Group IV A;
    from 0.1 to 6.0 % of a metal Group III A;
    from 0.1 to 10.0 % of an alkali or alkaline earth metal element;
    from 0.01 to 10.0 % of a halogen; and
    from 0.1 to 5.0 % of a metal Group VIII selected from Fe, Co and Ni provided on a high surface area meso or macroporous support. The the high surface mesoporous support comprises a spheroidal gamma alumina support with a diameter of 1.4 to 2.0 mm, a surface area in the range of from 150 to 220 m2/g, with bimodal narrow pore size distribution, water adsorption capacity in the range of from 1.4 to 2.5 ml/g, gamma crystallinity in the range of 60 to 80 % and a bulk density in the range of 0.25 to 0.4 g/ml.
