摘要:PCT No. PCT/JP96/01547 Sec. 371 Date Jan. 29, 1997 Sec. 102(e) Date Jan. 29, 1997 PCT Filed Jun. 7, 1996 PCT Pub. No. WO96/41678 PCT Pub. Date Dec. 27, 1996Vanadium-containing catalysts are obtained by using polyvanadic acid as a source of vanadium. Vanadium-containing catalysts are obtained by mixing catalyst components other than vanadium, or their precursors, with a polyvanadic acid sol which is formed by ion-exchanging a metavanadic acid aqueous solution with a proton-type cation-exchange resin and performing polycondensation, and by drying and/or calcining the mixture. Such vanadium-containing catalysts can fully exhibit their catalytic activity under mild reaction conditions, and can be suitably used for various reactions, such as synthesis of phthalic anhydride by the partial oxidation of o-xylene, synthesis of benzaldehyde by the partial oxidation of toluene, synthesis of benzoic acid by the partial oxidation of toluene, synthesis of anisaldehyde by the partial oxidation of p-methoxy toluene, synthesis of propylene by the oxidative dehydrogenation of propane, synthesis of isobutene by the oxidative dehydrogenation of isobutane, synthesis of methyl formate by the oxidative dehydrogenation of methanol, and synthesis of acrylonitrile by the ammoxidation of propane.

权利人:EXXON RESEARCH ENGINEERING CO
摘要:A vanadium, phosphorus oxygen containing catalyst composition capable of partially oxidizing hydrocarbons (e.g., n-butane) to form a carboxylic anhydride (e.g., maleic anhydride), a process for preparing this catalyst, and a process for using this catalyst to form such anhydrides is disclosed. The catalyst composition is prepared by an organic heterogenous technique followed by a water treatment step and activation.

标 题:Catalyst for production of hydrocarbons
发明人：GOODWIN JAMES G JR; ERI SIGRID; MARCELIN GEORGE; RIIS TRYGVE
权利人:NORSKE STATS OLJESELSKAP
摘要:A catalyst and process for converting synthesis gas composed of hydrogen and carbon monoxide to hydrocarbons. The catalyst includes cobalt in catalytically active amounts up to about 60wt% of the catalyst and rhenium in catalystically active amounts of about 0.5 to 50wt% of the cobalt content of the catalyst supported on alumina. A metal oxide promoter may be added. A preferred process includes the step of contact the synthesis gas feed with the catalyst at reaction conditions.
