Over the years, the quality of FCC charge stocks has continued to decline. The high levels of metals present in these feeds negatively affect catalyst performance and unit operations. Nickel and vanadium, in particular, act as catalyst poisons and can produce hydrogen and coke by-products. It is well recognized that nickel passivation of FCC Unit catalysts is a very effective way of reducing hydrogen and coke make. However, the actual passivation process and the critical variables that affect its performance should be well understood and adequately applied in order to assure maximum passivation benefit. The purpose of this paper is to present a detailed description of the nickel passivation process, how it works, and how it can be best applied, monitored, and optimized in terms of unit and chemical treatment performance. All variables critical to the understanding of the nickel passivation process are carefully addressed. Their relationships and proper application are demonstrated through examples of proven commercial applications.
