Abstract
Systems and methods for hydroprocessing a heavy oil feedstock are disclosed. The system employs a plurality of contacting zones and at least one separation zone, wherein a solvating hydrocarbon having a normal boiling point less than 538° C. (1000° F.) is employed. In the system, a mixture of heavy oil feedstock and solvating hydrocarbon is provided to a contact zone along with a slurry catalyst feed in a hydrocarbon diluent. The contacting zone operates at a temperature and pressure near the critical temperature and pressure of the heavy oil and solvating hydrocarbon mixture to convert at least a portion of the heavy oil feedstock to lower boiling hydrocarbons, forming upgraded products.
