    摘要： Siliceous zeolite catalysts comprising zeolitic mono- and/or divalent metal cations and a non-zeolitic Group VIII noble metal hydrogenating component supported thereon, which catalysts have undergone damage by thermal and/or hydrothermal stresses resulting in a maldistribution of the metal components, are rejuvenated in activity by a first treatment with a volumetric excess of aqueous ammonium hydroxide, followed by a second treatment with an extractive proportion of an aqueous ammonium salt solution. The combined treatments have a twofold effect of bringing about a desirable redistribution of the Group VIII noble metal, and of exchanging out at least a portion of undesired zeolitic mono- and/or divalent metal ions. A highly advantageous procedure for carrying out the rejuvenation involves simply neutralizing the ammonium hydroxide-catalyst mixture from the first treatment with a suitable acid to give the ammonium salt desired for the second treatment.

    摘要： PARAFFIN HYDROCARBONS ARE SELECTIVELY HYDROCRACKED AND ISOMERIZED UNDER CONTROLLED CONVERSION CONDITIONS BY CONTACTING THE HYDROCARBON WITH HYDROGEN, A CATALYST COMPOSED OF A FLUORIDED GROUP VII-B OR VIII METAL-ALUMINA CATALYST AND A CARBON OXIDE AS A CONVERSION REACTION MODERATOR. BY EMPLOYING A FLUORIDED METAL-ALUMINA CATALYST AND A CARBON OXIDE MODERATOR SUCH AS CARBON MONOXIDE OR CARBON DIOXIDE, PARAFFIN HYDROCARBONS ARE SELECTIVELY HYDROCRACKED AND ISOMERIZED IN A MANNER SUCH THAT SELECTIVE ITY, ACTIVITY AND PRODUCT DISTRIBUTION IS CONTROLLED OVER THE COURSE OF THE CONVERSION REACTION.

    摘要： A process for catalytically converting hydrocarbons wherein hydrocarbons are contacted at hydrocarbon conversion conditions with a supported iridium catalyst prepared by the contacting of, for example, an alumina support with a liquid medium containing a compound of iridium while maintaining the iridium-containing liquid medium at a pH of from 3 to 6 with an ammonium hydroxide or lower alkyl amine base.
