摘要
通过分析影响柴油超深度脱硫的主要因素,开发了柴油超深度加氢脱硫(RTS)工艺,并进行了RTS技术生产超低硫柴油工艺的中型试验研究。结果表明,采用RTS技术,通过工艺流程和操作条件优化,对以高硫直馏柴油为主的原料,可在比常规加氢精制工艺高50%以上的空速下生产出硫质量分数小于50μg/g、甚至小于10g/μg的超低硫柴油产品。RTS技术稳定性试验结果表明,RTS技术可以满足工业装置长周期运转的需要。
By analyzing the key factors influencing ultra-deep desulfurization of diesel fuel,a process for ul- tra-deep hydrodesulfurization of diesel （RTS） was developed. Studies on the process of RTS technology for pro- ducing ultra-low sulfur diesel fuels were carried out on a pilot plant unit. Results showed that by optimizing process flow and operation conditions, using feedstocks mainly containing high sulfur straight-run diesel, ultra- low sulfur diesel fuels with sulfur contents less than 50 μg/g and 10 μg/g could be obtained under high space velocity （50% higher than that of conventional hydroprocessing）. Stability test results showed that RTS technology could well meet the needs of long term operation in industrial unit.
