Patent ID: 7563357

Claim:
A process for cracking a synthetic crude oil-containing feedstock comprising: i) hydroprocessing a wide boiling range aliquot containing a) normally liquid hydrocarbon portion boiling in a range from about 50° to about 800° F., substantially free of resids, and b) thermally cracked hydrocarbon liquid boiling in a range from about 600° to about 1050° F., to provide a synthetic crude oil boiling in a range from about 73° to about 1070° F., containing greater than about 25 wt % aromatics, greater than about 25 wt % naphthenes, less than about 0.3 wt % S, less than about 0.02 wt % asphaltenes, and substantially free of resids other than asphaltenes; ii) adding to the synthetic crude oil a normally liquid hydrocarbon component boiling in a range from about 100° to about 1050° F. wherein the normally liquid hydrocarbon component is selected from the group consisting of light virgin naphtha, condensate, kerosene, distillate, hydrotreated gas oil, and hydrocrackate; and iii) cracking the mixture resulting from ii) in a cracker furnace comprising a radiant coil outlet to provide a cracked effluent, wherein the cracking is carried out under conditions sufficient to effect a radiant coil outlet temperature which is greater than the optimum radiant coil outlet temperature for cracking the synthetic crude oil separately.
