Abstract
A process for upgrading petroleum residuums by hydrogen diluent donor visbreaking employs coking of a higher boiling fraction of the visbreaker effluent wherein the hydrogen donor is also supplied to the coker feed either by excess feed to the visbreaker or by mixing a portion with the coker feed. Controlling the quantity of hydrogen donor in the visbreaker and coker feed proportionally controls the quantity of coke produced.
