摘要
An integrated process is provided herein having a first reaction zone to lower sulfur and nitrogen content of the initial feedstock to a target level to facilitate processing in a second reaction zone for deep hydrogenation. With the very low heteroatom content, noble metal catalyst materials used in the second reaction zone are protected and maximum saturation of aromatics is achieved. The processes and systems herein are suitable for converting certain heavy fractions, typically considered “low value” feedstocks, into higher value products including gasoline and diesel, and a hydrogen-rich, aromatic-lean heavy fraction suitable as feed for olefin production processes, or as a lubricant base oil.
