Zusammenfassung:The precipitation of sediment in the unconverted residuum derived from a virgin residuum conversion process is reduced significantly by blending with the unconverted residuum an effective amount of a virgin residuum having an asphaltene content of at least about 8% by weight of the virgin residuum at a temperature sufficient to render both residua during blending at a viscosity of no greater than 100 centistokes. A blend of 1-20% virgin residuum containing at least 8% asphaltene with 80-99% unconverted residuum from a virgin residuum conversion operation, which will contain little, if any sediment, can be used as heavy fuel for power plants.
