    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.

    摘要: Process for the preparation of a catalyst suitable for use in a naphtha reforming process, the process including providing a Y zeolite with an initial SiO2:Al2O3 molar ratio of at least 150, introducing the Y zeolite to a binder to form an intermediate composition, extruding the intermediate composition, reducing the alpha acidity of the extruded composition to provide a low acid composition, and introducing a noble metal to the low acid composition. Processes and systems of converting naphtha to a higher-octane hydrocarbon supply using catalysts, as prepared herein, are also disclosed.
