<p>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.</p> |
