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).

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.

摘要： Applicants have developed a new residuum full hydroconversion slurry reactor system that allows the catalyst, unconverted oil, hydrogen, and converted oil to circulate in a continuous mixture throughout an entire reactor with no confinement of the mixture. The mixture is separated internally, within one of more of the reactors, to separate only the converted oil and hydrogen into a vapor product while permitting the unconverted oil and the slurry catalyst to continue on into the next sequential reactor as a liquid product. A portion of the unconverted oil is then converted to lower boiling point hydrocarbons in the next reactor, once again creating a mixture of unconverted oil, hydrogen, converted oil, and slurry catalyst. Further hydroprocessing may occur in additional reactors, fully converting the oil. The oil may alternately be partially converted, leaving a concentrated catalyst in unconverted oil which can be recycled directly to the first reactor.

In one embodiment, high shear mixing is employed to generate an emulsion. In another embodiment, sulfiding is carried out at least twice for enhanced sulfiding. In another embodiment, at least a metal precursor feedstock is split into portions for addition in various stages of the process.
摘要翻译：提供了一种制备用于重油升级的浆料催化剂的方法。浆料催化剂的BET总表面积为至少100m 2 / g，总孔体积至少为0.5cc / g，多孔模数孔隙分布为至少80％孔径从5至2000埃。在一个实施方案中，将极性非质子溶剂与金属前体进料混合以形成油分散性前体。在另一个实施方案中，前体原料选自金属回收的压力浸出溶液，返修材料，双金属盐前体，单一金属前体中的任何一种。在一个实施方案中，采用高剪切混合来产生乳液。在另一个实施方案中，硫化进行至少两次以增强硫化。在另一个实施方案中，至少金属前体原料被分成用于在该方法的各个阶段中添加的部分。
