    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.

    摘要: There are provided a catalyst, a method for making this catalyst, and a process for using this catalyst in the alkylation of an isoparaffin with an olefin to provide an alkylate. The catalyst may be made from an as-synthesized material which, upon calcination, is capable of generating zeolites designated MCM-22. The as-synthesized material is then combined with a binder material, such as alumina, by an extrusion process. The uncalcined bound material may then be ammonium exchanged, followed by a calcination treatment. The as-synthesized material may also be swollen with a suitable swelling agent, such as a cetyltrimethylammonium compound, prior to the binding process.

    摘要: Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst system comprising a zeolite having the topology of ZSM-5 and a zeolite sorbing 10 to 40 mg 3-methylpentane at 90.degree. C., 90 torr, per gram dry zeolite in the hydrogen form, e.g., ZSM-22, ZSM-23, or ZSM-35. The treatment over the acidic catalyst system in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha.

    摘要: A method is described for preparing a molecular sieve-containing catalyst for use in a catalytic process conducted in a stirred tank reactor. The method comprises providing a mixture comprising a molecular sieve crystal and forming the mixture into catalyst particles having an average cross-sectional dimension of between about 0.01 mm and about 3.0 mm. The mixture may include a binder and the catalyst particles are then calcined to remove water therefrom and, after calcination and prior to loading the catalyst particles into a reactor for conducting the catalytic process, the catalyst particles are coated with a paraffin inert to the conditions employed in the catalytic process.
