A new concept for the proper interpretation of equilibrium microactivity test (MAT) performance data has been developed and designated UOP Dynamic Activity. It relates the MAT performance of the catalyst to the dynamics of the heat balance of the fluid catalytic cracker (FCC). Historically, the refining industry has relied heavily upon the MAT test to indicate the general conditions of the FCC equilibrium catalyst, and as a guide to catalyst management. Unfortunately, the MAT activity is commonly misinterpreted because of the indirect way the FCC catalyst interacts with the dynamics of the FCC heat balance. The importance of maintaining the FCC catalyst inventory in good health cannot be over emphasized. FCC catalyst directs the cracking reactions toward the desired products and maintains a desirable heat balance between the reactor and the regenerator through its interaction with the feed.
