Extraction of bitumen from oil sands |
| 摘要 |
Carbon disulfide is used as a solvent to extract bitumen from oil sands in an anhydrous countercurrent flow process that is compatible with existing procedures for upgrading bitumen. The solution is then treated in a thermal reaction to reduce viscosity and then fractionated to recover the bitumen. |

1. A process for the extraction of bitumen from oil sands comprising the steps of:
(a) contacting the oil sands with carbon disulfide to dissolve the bitumen, and separating solids from the solution; (b) hydrotreating the resulting solution by heating it to a temperature in the range of 200° to 300° C. in the presence of hydrogen; and (c) fractionating the hydrotreated solution to recover bitumen. |
