摘要： In a process for forming a bulk hydroprocessing catalyst by sulfiding a catalyst precursor made in a co-precipitation reaction, up to 60% of the metal precursor feeds do not react to form catalyst precursor and end up in the supernatant. In the present disclosure, the metals can be recovered via any of chemical precipitation, ion exchange, electro-coagulation, adding a precipitant to generate additional catalyst precursor, and combinations thereof to generate an effluent stream containing less than 50 mole % of metal ions in at least one of the metal residuals, and for at least one of the metal residuals is recovered as a metal precursor feed, which can be recycled for use in the co-precipitation reaction. The process results in minimal metals in the waste water stream. In one embodiment, an effluent stream to waste treatment contains less than 50 ppm metal ions.

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.
摘要翻译：公开了用于加氢处理重油原料的灵活的一次通过工艺。该方法采用多个接触区和至少一个分离区将至少一部分重油原料转化为较低沸点的烃，形成升级产物。接触区在加氢裂化条件下操作，使用浆状催化剂，其包含活性金属催化剂与重油原料的浓度大于500wppm的烃油稀释剂中平均粒度至少1微米的活性金属催化剂。多个接触区域和分离区域以可置换的方式配置，允许直通过程灵活地以各种模式操作：顺序模式; 并行模式; 并行和顺序模式的组合; 全部在线; 一些在线和一些待命; 一些在线和一些离线; 与来自接触区的流出物流平行的方式被送至与接触区串联的至少一个分离区; 与来自接触区的流出物流平行的方式与来自至少另一个接触区的流出物流合并并送至分离区; 以及它们的组合。在一个实施方案中，来自接触区的流出物串联送入下一个接触区用于进一步升级，其中下一个接触区具有至多100psi的压降，其中压降不是由于减压装置如在现有技术中那样。在一个实施方案中，至少选自抑制剂添加剂，消泡剂，稳定剂，金属清除剂，金属污染物去除剂，金属钝化剂和牺牲材料的添加剂材料的量小于1wt。将重油原料的％重量添加到至少一个接触区中。
