Temperature-programmed reduction (TPR) and high-temperature oxygen titration have been applied to characterize Ni and V in fluid cracking catalysts (FCC) as a function of catalyst composition and the method of metals impregnation and deactivation. The influence of the type of matrix, the level of ni
