Catalysts for FCC pretreatment are facing increasingly tougher feedstocks. This is partly the result of the general reduced availability of sweet crudes, and partly due to inclusion of larger amounts of unsaturated fractions such as coker gas oils. At the same time, process conditions are often limited by equipment designed for easier feedstocks. The result is that the requirements to the pretreating catalyst are today far more exacting. In this paper the authors demonstrate that the conversion of sulfur, nitrogen and polynuclear aromatics can be maximised by varying catalyst pore dimensions and/or particle size. Furthermore, it is shown that the optimum pore size depends on the reactivity of the feedstock and its diffusional properties. Whether or not it is advantageous to use smaller particles also depends on the properties of the feed.
