Zusammenfassung:Systems and methods for hydroprocessing a heavy oil feedstock, the system employs a plurality of contacting zones and separation zones and an interstage solvent deasphalting unit. The contacting zones operate under hydrocracking conditions, employing a slurry catalyst for upgrading the heavy oil feedstock, forming upgraded products of lower boiling hydrocarbons. In the separation zones which operates at a temperature within 20° F. and a pressure within 10 psi of the pressure in the contacting zones, upgraded products are removed overhead and optionally, further treated in an in-line hydrotreater. At least a portion of the non-volatile fractions recovered from at least one of the separation zones is sent to the interstage solvent deasphalting unit, for separating unconverted heavy oil feedstock into deasphalted oil and asphaltenes. The deasphalted oil stream is sent to one of the contacting zones for further upgrade.
