    摘要： A method for determining an amount of flocculant effective to recover a molecular sieve crystalline product that comprises the steps of (a) preparing a molecular sieve crystalline product mixture; (b) separating the molecular sieve crystalline product mixture into a plurality of samples; (c) mixing at least two of the plurality of samples with a quantity of flocculant to produce a plurality of flocculated samples, wherein at least two of the plurality of flocculated samples have a different ratio of flocculant to molecular sieve crystalline product mixture; (d) measuring the viscosity or zeta potential of at least two of the plurality of flocculated samples having a different ratio of flocculant to molecular sieve crystalline product mixture; (e) establishing a relationship between the quantity of flocculant and the viscosity or zeta potential measurements; and (f) determining from the relationship the amount of flocculant effective to recover the molecular sieve crystalline product.

    摘要： The present invention describes a method to increase the activity of a catalyst by first performing an ion exchange step with a potassium ion, followed by performing an ion-exchange step with an ammonium ion. Specifically, the present invention describes a method to increase the acidity of a zeolite by incorporating a potassium salt ion-exchange prior to an ammonium salt ion-exchange step. Even more specifically, the present invention is drawn to a method of increasing the activity of a zeolite by employing more than one potassium ion exchanges followed by at least one ammonium ion exchange. The present invention also describes a method to reduce the amount of sodium normally found in commercially produced zeolite by employing any of these methods. The present invention is also drawn to the catalysts produced by any of these methods.
