Abstract:
1. A method for increasing the maximum resid conversion and resid conversion rate in a resid hydrocracker upgrader comprising the steps: a) producing a hydrogen donor solvent precursor in said resid hydrocracker, wherein said precursor is produced by hydroreforming reactions; b) recovering hydrocracker cracked distillate oils by distillation and directing hydrocracker cracked resid product from said resid hydrocracker to a solvent deasphalting unit, wherein a resin stream containing said hydrogen donor solvent precursor is separated from oil and asphaltene species in said hydrocracker cracked resid product; c) directing said resin stream to a resid hydrotreater unit, wherein a hydrogen donor solvent is regenerated; and d) directing said hydrogen donor solvent to said resid hydrocracker upgrader.
