Abstract: Catalytic reforming is the main source of aromatics, but the reforming catalyst had low
selectivity for straight-chain alkanes and chlorine should be continuously replenished during
production process. Because of the above shortcomings, many domestic and foreign scholars turned to
study zeolitic reforming catalyst. The development of Pt/L, Pt/Mordenites, Pt/Beta and ZSM-5 zeolitic
reforming catalysts was summarized, and the advantages and shortcomings of these zeolitic catalysts
were analyzed as well. The performance and aromatic mechanism of ZSM-5 and L reforming catalyst
were particularly discussed. At last, the development trend of zeolitic reforming catalyst was discussed
It is pointed out that zeolitic reforming catalyst will replace the traditional catalyst inevitably. To
improve the catalyst stability by modifying the zeolite combined with deactivation mechanism is the
key to the development of zeolitic reforming catalyst. In addition, new zeolite materials should be
applied to the reforming catalyst in order to speed up industrialization process.
Key words: catalytic reforming; zeolite; catalyst; aromatization
