Description

[0001] Technical Field The present invention relates to a naphtha reforming catalyst containing bimetallic components and a preparation method thereof, specifically, a modified platinum-rhenium catalyst and a preparation method thereof. Background technique

[0002] Catalytic reforming is an important process for the production of high-octane gasoline components and aromatics from naphtha fractions. At the same time, the cheap hydrogen produced by the reforming process is also the main source of hydrogen for hydrogen processing units. In recent years, with the increasing social demand for reformed products, the production capacity of catalytic reforming units in the world has increased year by year, among which semi-regenerative reforming units still occupy a dominant position. Mass production has been widely used.

[0003] At present, the semi-regenerative reforming catalyst commonly used in industry is a platinum-rhenium bimetallic catalyst. Although the addition of rhenium ...
