Description:

The benefits that hydrotreating Fluidized Catalytic Cracking Unit (FCC) feed has on product yields and sulfur content were recognized some time ago and described in many earlier publications (2‐5). Recent regulatory demands and the drive towards clean fuels resulted in a renewed interest in FCC feed hydrotreating to facilitate compliance and satisfy the need for improved yields. To address these needs, Advanced Refining Technologies LLC (ART) introduced the ApARTTM Catalyst System for FCC pretreatment (6). This technology was developed to provide significant increases in HDS conversion while at the same time providing significant upgrading of FCC feedstock quality and has been described in detail previously (7). In essence, an ApARTTM Catalyst System is a staged bed of high activity NiMo and CoMo catalysts where the relative quantities of each catalyst can be optimized to meet individual refiner’s goals and constraints. ART has continued to develop a better understanding of the reactions and kinetics involved in FCC pretreating, and through its relationship with Grace Davison Refining Technologies, a detailed understanding of the effects of hydrotreating on FCC unit performance. The complexity of combinations of catalyst design and operating conditions for both the FCC feed hydrotreater and the FCC unit continues to present a significant optimization opportunity for refiners to drive the combined operation to maximum product value.
