ABSTRACT:
Asphaltene-containing hydrocarbonaceous black oils are subjected to conversion conditions in a two-stage process. The physical characteristics of the catalytic composite disposed within the individual stages, or reaction zones, are different. This difference in physical characteristics is directed toward macropore volume, and is maintained whether the chemical composition is the same, or varies.
