    摘要: A process for a shape selective hydrocarbon conversion such as toluene disproportionation involves contacting a reaction stream under conversion conditions with a catalytic molecular sieve which has been pre-selectivated and concurrently activated by contact with a substantially aqueous solution of an organosilicon compound. The invention also includes a method for concurrently preselectivating and activating a catalyst and the shape selectivated, activated catalyst which results from this method.

    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.
