FD2G加氢转化技术研发及应用

目前我国炼油市场柴汽比下降、环保法规日趋严格,催化柴油(LCO)油品价值降低,炼油企业急需调整产品结构,为其寻找新的出路。而国内面临着高辛烷值汽油短缺的情况,因此将催化柴油转化为高辛烷值汽油是一条降低柴汽比、增产汽油的有效途径。结合催化柴油的性质从反应机理、试验数据及工业应用等方面介绍了FD2G加氢转化技术。结果表明:FD2G加氢转化技术可将催化柴油加氢转化为高辛烷值汽油和清洁柴油调和组分,同时可生产轻质芳烃原料等高附加值产品。

R & D and Application of FD2G Hydroconversion technology

At present, China's refining market diesel/gasoline ratio is decreasing and environmental regulations are becoming increasingly tight, the value of FCC light cycle oil(LCO) has been decreased, oil refining enterprises need to adjust the product structure to look for a new way for it. While facing the high octane number gasoline shortages in China, so converting LCO into high-octane gasoline is a effective method for reducing diesel/gasoline ratio and increasing gasoline. In this paper, combined with properties of LCO, FD2G hydrogenation technology was introduced from the aspects of reaction mechanism, test data and industrial application. The results show that the FD2G hydrogenation technology can convert LCO into high-octane gasoline and cleaner diesel components, and can produce light aromatic hydrocarbon raw materials and other products with high added value.
