Abstract
Disclosed is a catalytic process for hydroconverting heavy hydrocarbonaceous feedstocks to lower boiling products wherein a catalyst precursor concentrate or catalyst concentrate is first prepared in a heavy oil medium then fed to a hydroconversion zone which may also contain a supported hydrotreating catalyst. The hydroconversion zone may be operated in either slurry or ebullating bed mode.
