Stacked Bed Hydrotreating Reactor System

摘要

Methods and systems for diesel formation are described herein. The diesel hydrotreating systems generally include a hydrodesulfurization unit having a catalyst system disposed therein and adapted to contact an input stream with the catalyst system therein to form diesel. The catalyst system generally includes a plurality of catalysts including a first catalyst including a hydrodesulfurization catalyst having a first pore diameter and a second catalyst having a second pore diameter, wherein the second pore diameter is larger than the first pore diameter.
