摘　　要：根据反应工程原理开发了气液逆流加氢生产超低硫甚至无硫低芳烃柴油新工艺,考察了工艺参数对加氢脱硫、脱芳烃效果的影响。研究表明:氢分压、反应温度、体积空速对柴油逆流加氢工艺的影响和常规并流工艺基本一致,但氢油体积比在一定的范围内对两种工艺的影响差异很大。试验结果证明,气液逆流加氢具有更高的脱硫、脱芳烃深度,是一种经济有效的先进加氢精制工艺。The Flash with Countercurrent Sulfur-compounds Hydrogenation process （FCSH） has been successfully developed based upon reaction engineering mechanisms and impacts of process parameters on desulfurization and dearomatization rates are investigated. The temperature, volumetric space velocity have the similar the conventional co-current hydrogenation process. The study shows that the hydrogen partial pressure, reactor impact on countercurrent hydrogenation process as on tests reveal that the gas-liquid countercurrent process offers higher desulfurization and dearomatization efficiency and is a cost-effective hydrotreating process.
