    摘要: The present invention provides a process for modifying a crystalline aluminosilicate zeolite having a Constraint Index of from about to about 12 which comprises:(a) steaming the as synthesized crytalline aluminosilicate zeolite containing organic template material to decompose at least a portion of said template material and to extract zeolitic aluminum; and,(b) contacting the zeolite resulting from step (a) in the ammonium, alkali metal or hydrogen form with a dealuminizing agent which forms a water-soluble complex with aluminum to remove a further quantity of zeolitic aluminum therefrom wherein said treated catalyst is employed in the making of lube oil from olefins.

    摘要: An improved process for the production of unsaturated carboxylic acids and unsaturated nitriles from their corresponding C3 to C5 alkanes, or mixtures of C3 to C5 alkanes and alkenes, that involves oxidation in the presence of a supported Mo—V-based mixed metal oxide catalyst in a multi-stage reaction system which employs both separation of the oxidation product from one or more intermediate effluent streams, as well as feeding additional oxygen to reaction zones subsequent to the first reaction zone.
