Reforming catalyst compositions

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.

1. A process for the preparation of a catalyst suitable for use in a naphtha reforming process comprising:
(a) providing a Y zeolite with an initial SiO2:Al2O3 molar ratio of at least 150; (b) introducing the Y zeolite to a binder to form an intermediate composition; (c) extruding the intermediate composition; (d) reducing the acidity of the extruded composition to provide a low acid composition such that the alpha acidity of the low acid composition is less than about 1.25; and (e) introducing a noble metal to the low acid composition; wherein the noble metal is selected from the group consisting essentially of platinum, rhenium, iridium, or combinations thereof, wherein the noble metal is introduced to the low acid composition via impregnation in a rotating impregnation cone; and wherein the catalyst suitable for use in a flaptha naphtha reforming process is chlorine free.
