Abstract
Abstract The kettle residue oil containing entrained catalyst from the fractionation of catalytically converted hydrocarbon oil is passed through a settler and then centrifuged to produce an oil of suitably low ash content. The catalyst from the settler and the catalyst fines from the centrifugation are recycled to the reactor thereby eliminating the disposal of an oily catalyst residue. In one embodiment of the invention, an oil of suitably low ash content to serve as a carbon black production feedstock is produced.
