摘要：
Using the high voltage industrial frequency current to heat oil shale, the plasma channels can be formed in oil shale. The in-situ cracking of oil shale is realized by heating the oil shale with the generated plasma and the carbonized inner surface of the conductive channel. In this paper, a three-dimensional coupled model of oil shale was established by finite element analysis software, and the distribution of temperature field during the high frequency oil shale pyrolysis was obtained by numerical calculation. When the voltage is 1 000 V and the current is 5 A, the temperature at the center of electrode, after 6 minutes heating, reached 597℃, and the temperature at the areas around the electrode 30 mm away reached 347℃, meeting the pyrolysis demand of oil shale. With the increase of current, the increased temperature of oil shale during the same heating time showed a steady rise, and the range of effective pyrolysis also went up. According to the results of numerical simulation, using the high voltage industrial frequency to heat oil shale can gain a fast heating rate and high energy efficiency. © 2019, Editorial Department of Journal of Northeastern University.
