    摘要: This invention relates to a new catalyst and to a novel oxidation process. In this novel process, aromatic compounds with an alkyl group having at least one alpha hydrogen, including aromatic compounds wherein the alkyl groups are unsubstituted and substituted, are contacted in the liquid phase at reaction conditions with an oxygen-containing gas in the presence of a novel catalyst which is prepared by milling an anhydrous transition metal halide with silver nitrite, the transition metal being selected from the Groups IVb to VIII and Ib and IIb of the Periodic Table, wherein the mole ratios of metal halide to silver nitrite are in the ratio of 1:1 to 1:5.

    摘要: A process for hydrotreating (hydroprocessing) hydrocarbons and mixtures of hydrocarbons utilizing a catalytic composite comprising a porous carrier material containing, on an elemental basis, about 0.01 to about 2 wt. % platinum group metal, about 0.5 to about 5 wt. % cobalt, about 0.01 to about 5 wt. % tin and about 0.1 to about 3.5 wt. % halogen, wherein the platinum group metal, cobalt and tin are uniformly dispersed throughout the porous carrier material, wherein substantially all of the platinum group metal is present in the elemental metallic state, wherein substantially all of the tin is present in an oxidation state above that of the elemental metal, and wherein substantially all of the cobalt is present in the elemental metallic state or in a state which is reducible to the elemental metallic state under hydrocarbon conversion conditions, in which process there is effected a chemical consumption of hydrogen. A specific example of one such catalyst is a composite of a crystalline aluminosilicate, a platinum group metal component, a cobalt component, a tin component, and a halogen component, for utilization in a hydrocracking process. Other hydrocarbon hydroprocesses are directed toward the hydrogenation of aromatic nuclei, the ring-opening of cyclic hydrocarbons, hydrogenation, etc.

    摘要: Hydrocarbon conversion is effected in the presence of a catalyst consisting essentially of graphite having intercalated in the lattice thereof between about 5 and about 75 weight percent of a Lewis acid. The catalyst may additionally have intercalated therein a minor proportion of a Bronsted acid and/or a Group VI-B or Group VIII metal. The catalyst of graphite having the specified components intercalated in its structure is shown to be much more effective in hydrocarbon conversion, e.g. isomerization, than catalysts having said components deposited on the surface of the graphite.

    摘要: A process for producing an aromatic carboxylic acid by liquid-phase oxidizing an alkylbenzene with a molecular oxygen-containing gas in a lower aliphatic carboxylic acid solvent in the presence of a heavy-metal-bromine oxidation catalyst, in which the oxidation reaction is conducted using a material containing as inorganic elements only cobalt, manganese, and bromine as the catalyst components and while withdrawing from the reaction system, at least partially, the condensed liquid of a gaseous mixture discharged from the top of the reactor during the reaction and maintaining the water content of the reaction system below a definite level by introducing fresh solvent (or, preferably, the solvent recovered as a side cut fraction by distilling the condensed liquid) in an amount corresponding to the amount of the solvent withdrawn contained in the condensed liquid, and a reaction mother liquor which is formed by separating the aromatic carboxylic acid from the reaction mixture withdrawn from the reactor is recycled, as it is, to the reactor for reuse in the oxidation reaction.

    摘要: Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a trimetallic acidic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a Group IVA component, a bismuth component and a halogen component with a porous carrier material. The platinum group component, Group IVA metallic component, a halogen component are present in the trimetallic catalyst in amounts respectively, calculated on an elemental basis, corresponding to about 0.01 to about 2 wt. % platinum group metal, about 0.01 to about 5 wt. % Group IVA metal and about 0.1 to about 3.5 wt. % halogen. The bismuth component is present in amounts corresponding to an atomic ratio of bismuth to platinum group metal of about 0.1:1 to about 1:1. Moreover, these metallic components are uniformly dispersed throughout the porous carrier material in carefully controlled oxidation states such that substantially all of the platinum group metal and bismuth components are present therein in the corresponding elemental metallic states while substantially all of the Group IVA metallic component is present therein in an oxidation state above that of the corresponding metal. A specific example of the type of hydrocarbon conversion process disclosed is a process for the catalytic reforming of a low-octane gasoline fraction wherein the gasoline fraction and hydrogen stream are contacted with the novel trimetallic catalyst disclosed herein at reforming conditions.
