Abstract: Fushun shale oil as the research object was investigated. In laboratory an ultrasonic demulsification technology was used to intensify demetalization of shale oil. The effect of various parameters on demetalization of Fushun shale oil were discussed, which were ultrasound-assisted, demetalization agent type and dosage, demulsifier type, subsidence time on the removal of the Fe, Ca, Na and Mg impurity. The demetalization effect with ultrasonic radiation was much better than that without under the suitable conditions. In ultrasonic radiation, the metal removal effect is the best when the demetallization agent(ETCF) mass fraction was 2 500 μg/g and demulsifier R203A, the settling time was 4 h. Under these condition the removal rate of Fe is 80%, and the removal rate of Mg is 90%.

摘要： 以抚顺页岩油为研究对象，在实验室条件下，采用超声波破乳技术进行页岩油脱金属的研究。研究了超声波的辅助作用、脱金属剂种类及其用量、破乳剂种类、沉降时间等因素对金属Fe，Ca，Na和Mg脱除率的影响，得出了较为理想的脱金属工艺参数。结果表明，在超声波与无超声波作用下，前者脱金属效果较后者显著；在超声波作用下，脱金属剂ETCF的质量分数为2 500 μg/g，破乳剂选用R203A，沉降4 h，金属Fe脱除率达到80%以上，金属Mg脱除率达到90%以上。
