Conversion of sulfur, nitrogen, and polynuclear aromatics can be optimized by varying catalyst pore dimensions and/or particle size. Increased workload and more exacting performance are demanded from today's fluid catalytic cracking feed pretreat catalysts. The desire to process heavier crudes and the inclusion of visbreaker gas oil, unsaturated fractions like coker gas oils, and even resid, have placed greater emphasis on the importance of selection of those catalysts. Also, some older plants are limited to process conditions and equipment designed for easier feedstocks. Data show that the optimum catalyst pore size for a given application depends not only on the reactivity of the feed, but also on the catalyst's diffusional properties. These properties are also factors which determine whether or not a change in catalyst particle size would be advantageous.
