The effects of metal poisons (Ni, V) on zeolitic cracking catalyst have been investigated with the goal of developing a method for determining the inherent metal resistance of different catalyst compositions in the laboratory. Metal resistance is evaluated by determining activity and selectivity both before and after a synthetic poisoning procedure so that ''contaminant yields'' - the excess coke and hydrogen produced by metals during cracking - could be calculated. After several methods are compared, that chosen involves impregnation of steam-deactivated catalysts with a gas oil doped with metal naphthenates, followed by high-temperature cracking and regeneration.
