A method for preparing a mixture of FCC catalyst components for use in an FCCU, which comprises: performing an analysis of an FCCU operation; determining the catalyst requirements for the FCCU, based on said analysis; determining the catalytic properties of at least two FCC catalyst components selected from the group consisting of untreated equilibrium FCC catalyst, reactivated equilibrium FCC catalyst, demetallized equilibrium FCC catalyst, reactivated and demetallized equilibrium FCC catalyst and fresh high activit y FCC catalyst containing a zeolite component; and blending said at least two components in proportions, based on the determined properties of said at lea st two components and the determined catalyst requirements, to form a mixture o f the components suitable for addition to the FCCU.
