Hydrocracking of asphaltene-rich bitumen residuums |
(57) A process is provided for selectively converting the asphaltene-rich fraction of
a hydrocarbon residuum to a refinery treatable product. The bitumen residuum is concentrated
to provide an asphaltene-rich feedstock. The feedstock is admixed with a thermally
decomposable catalyst precursor and preheated to a temperature of between about 200
oC - 300
oC under ambient conditions to convert said precursor to an active colloidal catalyst.
The mixture is reacted with hydrogen under hydrocracking conditions at a temperature
of between 420
oC-490
oC to thereby selectively hydrocrack the asphaltene fraction.
