ABSTRACT:
Heavy oils are advantageously preconditioned by heat soaking prior to hydrotreating with a dispersed metal catalyst to reduce coking in a two stage hydrotreating process. The effluent of a hydrotreating process is filtered to recover catalytically active coke which is recovered by backflushing and recycled to the feed stream. A mild solvent deasphalting step isolates metals in a reduced volume asphaltene fraction.
