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%.
