| Title |
Process for selective recovery of relatively metals-free bitumen from tar sand using a halogenated aliphatic solvent in combination with a second solvent |
| Date |

| Description |
A process for the selective recovery of tar sand bitumen from tar sands using a two-solvent system comprising a halogenated aliphatic solvent in combination with a second solvent selected from an oxygenated compound. The process provides for an inexpensive method for selectively removing substantially metal-free tar sand bitumen from tar sands. The bitumen so recovered renders the same amenable to catalytic desulfurization and upgrading processes. |
