    • Embodiments of apparatuses and methods for hydrotreating coker kerosene or other thermally or catalytically cracked hydrocarbon stream are provided. In one example, a method comprises splitting a feed comprising coker kerosene into first and second feed streams. The first feed stream is heated to form a heated first feed stream. The second feed stream is partially heated to form a partially heated second feed stream. The heated first feed stream is contacted with a first hydrotreating catalyst to form a first hydrotreated intermediate stream. The first hydrotreated intermediate stream is combined with the partially heated second feed stream to form a partially quenched first hydrotreated intermediate combined stream. The partially quenched first hydrotreated intermediate combined stream is contacted with a second hydrotreating catalyst to further hydrotreat the partially quenched first hydrotreated intermediate combined stream.
    • 提供了用于加氢处理焦化煤油或其他热或催化裂化烃物流的装置和方法的实施方案。 在一个实例中,一种方法包括将包含焦化煤油的进料分成第一和第二进料流。 将第一进料流加热以形成加热的第一进料流。 第二进料流被部分加热以形成部分加热的第二进料流。 加热的第一进料流与第一加氢处理催化剂接触以形成第一加氢处理的中间流。 将第一加氢处理的中间物流与部分加热的第二进料流合并以形成部分骤冷的第一加氢处理的中间混合料流。 将部分骤冷的第一加氢处理的中间混合料流与第二加氢处理催化剂接触,以进一步加氢部分骤冷的第一加氢处理的中间混合料流。
