本研究考察了高硫石油焦在真空条件下的脱硫率。研究了不同喂料层深度、热处理温度、保温时间、颗粒大小和真空度。加料层对脱硫率有显著影响，最佳加料层为30 mm。当温度为1500℃、保温时间为2小时、−粒径为150μm、真空度为1℃时，催化剂的脱硫率较高。结果表明，真空的应用提高了脱硫率。更重要的是，可以获得元素硫，而不是传统的高温焙烧脱硫过程中产生的SO2排放。最后，用X射线衍射仪分析了石油焦脱硫的机理。
In this research, the sulfur removal efficiency from high-sulfur petroleum coke in the presence of vacuum was investigated. Different feeding layer depth, heat treatment temperature, holding time, particle sizes, and vacuum degree were studied. The feeding layer has a significant effect on the sulfur removal rate, and the optimal feeding layer was 30 mm. A higher sulfur removal rate was obtained at 1500 °C, with a holding time of 2 h, particle sizes of −150 μm, and 1 Pa vacuum. It was evident that the application of vacuum improved the sulfur removal efficiency. More importantly, elemental sulfur can be obtained instead of SO2emission that occurs during traditional desulfurization by high-temperature calcinations. Finally, the mechanism of sulfur removal from petroleum coke was analyzed by XRD.
