Abstract
This invention provides a process for upgrading a heavy hydrocarbon oil to motor fuel products. The heavy hydrocarbon oil is admixed with a metal halide catalyst and a solvent component under supercritical conditions to form (1) a dense-gas solvent phase which contains refined hydrocarbon crackate, and which is substantially free of metal halide catalyst content; and (2) a residual asphaltic phase.
Claims28
A process for conversion of a heavy hydrocarbon oil which comprises (1) contacting a heavy hydrocarbon oil with a metal halide catalyst in admixture with a solvent component under supercritical conditions to form a dense-gas solvent extract phase and a residual asphaltic phase;
- (2) separating the phases to provide a dense-gas solvent extract phase which is substantially free of metal halide catalyst content;
- and (3) fractionating the dense-gas solvent extract phase to remove the solvent and yield a refined hydrocarbon crackate fraction.
A process for conversion of a heavy hydrocarbon oil which comprises (1) contacting a heavy hydrocarbon oil with a metal halide catalyst in admixture with an in situ-formed solvent component under supercritical conditions to provide a dense-gas solvent extract phase and a residual asphaltic phase;
- and (2) separating the phases to yield a dense-gas solvent extract phase which is substantially free of metal halide catalyst content.
