Abstract: In order to meet the requirement of moving-bed light hydrocarbon aromatization for the continuous flow performance of catalyst, a spherical zeolite catalyst RF-4 with independent intellectual property was developed by SINOPEC Research Institute of Petroleum Processing. The new catalyst exhibited excellent catalytic performance and continuous flow properties, such as high aromatization activity, high crushing strength, high spherical degree and good regeneration performance, which broke through the key technology in the development of moving-bed light hydrocarbon aromatization. The results of industrial application showed that catalyst RF-4 had excellent activity and stability in the moving-bed aromatization unit with light hydrocarbons as raw materials, and it had broad application prospects.

Key words: moving bed, light hydrocarbon, aromatization, sphere catalyst, crushing strength
