ABSTRACT:
The sulphur emissive capability, on combustion, of coke which is formed during upgrading of sulphur-containing heavy crude oils, including oil sands bitumen, or residua is decreased by the addition of slaked lime or calcium oxide to the heavy crude oil prior to coking. The presence of the slaked lime or calcium oxide leads to an increased yield of liquid distillates at coking temperatures of about 450.degree. to about 500.degree. C. Ash remaining after combustion of the coke may be leached to recover nickel and vanadium values therefrom.
