Abstract: Based on the prediction of the effect of olefin and aromatics content decrease in high octane components leading to the decrease of octane number of gasoline due to the upgrading of gasoline quality, the relative surplus of naphtha and the change of aromatics supply structure caused by light hydrocarbons and shale gas as steam cracking feedstocks, and the challenges of national development strategy of new energy and new energy vehicles to traditional refining industry, the idea of light hydrocarbon and naphtha comprehensive utilization technology is put forward. According to the concept of transformation development and molecular refining, a series of technologies, such as light hydrocarbon dehydrogenation, light hydrocarbon aromatization, C₅-C₆ isomerization and naphtha catalytic reforming, have been developed and industrialized. Through the integration of these technologies and traditional technologies, the product scheme can be flexibly adjusted.

Key words: dehydrogenation, isomerization, aromatization, catalytic reforming
