    摘要: A process for producing aliphatic amines which comprises reacting an aliphatic alcohol or an aliphatic aldehyde with an aminating agent selected from the group consisting of ammonia, a primary amine and a secondary amine in the liquid phase in the presence of an unsupported catalyst consisting essentially of (1) copper oxide or copper hydroxide and (2) a Group II A metal oxide or hydroxide. In a preferred embodiment the catalyst system also contains an organo nickel compound.

    摘要: Maleic anhydride is produced by passing a C.sub.4 to C.sub.12 hydrocarbon stream together with molecular oxygen over a fixed bed containing a vanadium molybdate catalyst promoted with a novel cobalt niobate having the formulaCoNb.sub.a O.sub.xwherein a is a number from about 1.0 to about 4.0 and x is a number from about 3.5 to about 11.0. The catalyst is prepared by calcining a slurry containing cobalt oxide and niobium oxide, or their precursors, in at a temperature range from about 400.degree. to about 1200.degree. C. for about 1 to about 40 hours to obtain a cobalt niobate, which is then slurried with a mixture of oxides of vanadium and molybdenum, or their precursors, dried, and then calcined at a temperature from about 300.degree. to about 650.degree. C. for about 0.5 to about 24 hours. A support cam can be used for the catalyst.

    摘要: A catalytic reforming process is disclosed using a catalyst containing a Group VIII metal, low amounts of bismuth, and a zeolite L. The catalyst is a non-acidic, monofunctional reforming catalyst. Preferably, the catalyst contains one or more halogens. Preferably, the feed includes C.sub.8 hydrocarbons. The addition of small amounts of bismuth increase or substantially maintain catalyst stability. Unexpectedly low dealkylation rates are achieved using the catalyst while reforming to produce aromatics, especially to produce xylenes such as paraxylene.

    摘要: A high temperature treatment process is disclosed for increasing conversion and reducing the fouling rate of reforming catalysts. The process comprises reducing the catalyst in a reducing gas atmosphere at a temperature below 1025.degree. F. and then treating the reduced catalyst at a temperature of from 1025.degree. F. to 1275.degree. F. in an inert gas atmosphere.
