轻烃及石脑油综合利用技术开发及工业应用

分析了汽油质量升级过程中高辛烷值组分烯烃和芳烃含量的降低对汽油辛烷值下降的影响，轻烃及页岩气作为蒸汽裂解原料带来的石脑油相对过剩及芳烃供给结构的变化，新能源及新能源车的国家发展战略对传统炼油行业的挑战；提出了轻烃及石脑油综合利用技术的开发思路，按照转型发展及分子炼油的理念，开发了轻烃脱氢、轻烃芳构化、C₅~C₆异构化及石脑油催化重整成套技术等系列技术，并实现了工业化。通过这些技术与传统技术的集成，可以灵活调整产品方案。

DEVELOPMENT AND INDUSTRIAL APPLICATION OF LIGHT HYDROCARBON AND NAPHTHA COMPREHENSIVE UTILIZATION TECHNOLOGY

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.
