Study on ultrasonic extraction of kerogen from Huadian oil
The optimum operating parameters are determined by the orthogonal test and are the following: 60 kHz ultrasonic frequency, 200 W ultrasonic power, 30 min extraction time, and 313 K extraction temperature. The oil yield by the ultrasonic extraction of Huadian oil shale can reach 15.6% based on the demineralized oil shale.
