Abstract
Systems and methods are provided for use of coking and slurry hydroconversion for conversion of heavy oil feeds. The combination of coking and slurry hydroconversion allows for improved yield of liquid products while reducing or minimizing the consumption of hydrogen in slurry hydroconversion reaction stages. Coking and slurry hydroconversion can be combined by segregating feeds based on Conradson carbon residue. Alternatively, slurry hydroconversion can be used to process unconverted bottoms from a coking process.
