摘要： A flexible once-through process for hydroprocessing heavy oil feedstock is disclosed. The process employs a plurality of contacting zones and at least a separation zone to convert at least a portion of the heavy oil feedstock to lower boiling hydrocarbons, forming upgraded products. The contacting zones operate under hydrocracking conditions, employing a slurry catalyst which comprises an active metal catalyst having an average particle size of at least 1 micron in a hydrocarbon oil diluent, at a concentration of greater than 500 wppm of active metal catalyst to heavy oil feedstock. The plurality of contacting zones and separation zones are configured in a permutable fashion allowing the once-through process to be flexible operating in various modes: a sequential mode; a parallel mode; a combination of parallel and sequential mode; all online; some online and some on stand-by; some online and some off-line; a parallel mode with the effluent stream from the contacting zone being sent to at least a separation zone in series with the contacting zone; a parallel mode with the effluent stream from the contacting zone being combined with an effluent stream from at least another contacting zone and sent to the separation zone; and combinations thereof. In one embodiment, the effluent from a contacting zone is sent to the next contacting zone in series for further upgrade, with the next contacting zone having a pressure drop of at most 100 psi, with the pressure drop is not due to a pressure reducing device as in the prior art. In one embodiment, at least an additive material selected from inhibitor additives, anti-foam agents, stabilizers, metal scavengers, metal contaminant removers, metal passivators, and sacrificial materials, in an amount of less than 1 wt. % of the heavy oil feedstock, is added to at least one of the contacting zones.

In the separation 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 recycled back to the first contacting zone in the system, in an amount ranging between 3 to 50 wt. % of the heavy oil feedstock. In one embodiment, at least some of the heavy oil feedstock is supplied to at least a contacting zone other than the first contacting zone and / or at least some of the fresh slurry catalyst is supplied to at least a contacting zone other than the first contacting zone. In one embodiment, 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.

摘要： A method to upgrade heavy oil feedstock using an ebullated bed reactor and a novel catalyst system is provided. The ebullated bed reactor system includes two different catalyst with different characteristics: an expanded catalyst zone contains particulate catalyst having a particle size of greater than 0.65 mm; and a slurry catalyst with average particle size from 1 to 300 µm. The slurry catalyst is provided to the ebullated bed system with the heavy oil feedstock, and entrained in the upflowing hydrocarbon liquid passing through the ebullated bed reaction zone. The slurry catalyst reduces the formation of sediment and coke precursors in the reactor system. In one embodiment, the slurry catalyst is prepared from at least a water-soluble metal precursor, which is pre-sulfided or sulfided in-situ. In another embodiment, the slurry catalyst is prepared from rework materials (catalyst fines).
