Research Status of Continuously Regenerated Reforming Catalysts

The in-depth development of semi-regenerative reforming catalysts and process technology has gradually exposed shortcomings such as high pressure in the reaction system, low reaction temperature, catalyst shutdown and regeneration, and operating conditions that need to be adjusted according to the degree of carbon deposition of the catalyst. Although through the development of new catalysts, Many efforts such as the application of segmental filling technology, but still cannot fundamentally solve its own inherent shortcomings. Through in-depth research on the catalytic reforming process, UOP launched a unique continuous reforming technology in the early 1970s, thus bringing the catalytic reforming technology into a new era.
In 1986, my country's first continuous reforming catalyst 3861 was successfully scaled up in industry. French IFP confirmed that 3861 catalyst had good performance and could be used in the imported continuous reforming industrial device using French IFP technology.
In 1994, GCR-10 catalyst was industrialized in the continuous reforming unit of Guangzhou Petrochemical Plant using UOP technology. Subsequently, my country successfully developed a series of continuous reforming catalysts, which have reached the world advanced level in the research and development of continuous reforming catalysts. The main products are PS series catalysts. The progress of continuous reforming catalysts has promoted the continuous reforming process to the super Low pressure high harsh direction. The reaction pressure is reduced from 1.2 MPa to 0.35 MPa, and the molar ratio of hydrogen to oil is reduced from 5:1 to 2:1.
The new idea of researching continuous regeneration reforming catalysts is to start with new catalytic materials, new reaction systems, catalysts suitable for capacity expansion of old reforming units, continuous reforming catalysts with high aromatization selectivity, and develop catalysts with good selectivity, initial activity and regeneration performance .
