ABSTRACT:
Middle distillate petroleum streams are hydrotreated to produce a low sulfur and low aromatic product in a process employing two reaction zones in series. The effluent of the first reaction zone is purged of hydrogen sulfide by hydrogen stripping and then reheated by indirect heat exchange. The second reaction zone employs a sulfur-sensitive noble metal hydrogenation catalyst. Operating pressure and space velocity increase and temperature decreases from the first to second reaction zones.
