Desulfurization method of heavy oil using supercritical extraction |
| abstract |
The present invention relates to a heavy oil desulfurization method using supercritical extraction, and more particularly, by adding a hydrocarbon solvent to the heavy oil containing a sulfur-containing compound, extracting and separating the sulfur-containing compound from the heavy oil under supercritical conditions. While obtaining desulfurized heavy oil without using hydrogen and catalyst of It relates to a method of desulfurization of heavy oil that can improve the efficiency of the process by being simple compared to the present invention. |
