Upgrading of high boiling hydrocarbons

Patent ·
OSTI ID:5918555
;
A process is described for upgrading a high boiling hydrocarbon, comprising: deasphalting the high boiling hydrocarbon to recover as separate fractions, deasphalted oil, resin and pitch; upgrading the resin fraction to produce an effluent containing upgraded product and high boiling components; recovering high boiling components from the effluent; subjecting the deasphalting at least a portion of the recovered high boiling components to reject coke precursors in the (pitch fraction) high boiling components portion prior to recycle thereof to the upgrading with the resin fraction; and thereafter recycling the high boiling components portion with the resin fraction to the upgrading.
