ABSTRACT:
A process for upgrading bitumen asphaltenes obtained from tar sands to hydrocarbons which comprises contacting the bitumen with a deasphalting solvent to yield a deasphalted oil and a residual solid asphaltene, separating the residual solid asphaltene from the deasphalted oil and treating the solid asphaltene fraction with superheated water at temperatures of from 300.degree. to 425.degree. C.
