Abstract: A method is provided to produce a clean resid from a heavy hydrocarbon, the method including the steps of: feeding a heavy hydrocarbon to a conversion unit to convert at least a portion of the heavy hydrocarbon to lighter products and producing a resid, the resid comprising at least ten percent by weight components having true boiling points greater than 380° C. and further comprising at least some asphaltenes; contacting the resid with a naphtha to produce a mixed naphtha and resid, the naphtha comprising paraffin having from four to twelve carbons, the ratio of naphtha to resid high enough to result in precipitation of at least a portion of the asphaltenes in the resid; and separating a reject stream comprising asphaltenes and at least some solids from the resid to form a clean resid.
