OSTI ID:5390782
A petroleum refinery vacuum residuum stream is subjected to hydrogen donor diluent cracking, and the liquid cracking effluent is hydrodesulfurized. The hydrodesulfurizer effluent is then fractionated, and the fractionator bottoms stream is fed to a delayed coker where premium type delayed coke is produced. The gas oil boiling range fraction from the fractionator is utilized as the donor diluent in the cracking step.
