ABSTRACT:
Distress feeds, such as refinery sludge and slop oils are upgraded over hot equilibrium catalyst (E-Cat) removed from an FCC regenerator. Hot E-Cat demetallizes and/or demulsifies slop and sludge streams in an auxiliary reactor without contaminating the FCC catalyst inventory. Waste streams are upgraded with a "waste" catalyst stream. The auxiliary reactor and FCC reactor may share a product fractionator.
