1. A method comprising:
developing a model to predict catalytic performance using any flushing content and quality in the catalytic inventory of residue fluid catalytic cracking (FCC) units;
modifying a process simulator for residue FCC units with the model developed in (1) for operation with any flushing content and quality in its catalytic inventory;
implementing the model into the process simulator to obtain a refining production planning model.
