Abstract
The present study reports the catalytic cracking of cumene using a novel CREC Riser
Simulator. Two sizes of zeolite crystals (0.4 and 0.9 m) are employed in the experiments. The
goal is to develop and test, under relevant reaction conditions for FCC (temperature, contact
time, reactant partial pressure, catalyst /oil ratio), a new catalytic activity decay model based
on "reactant conversion". Kinetic and decay model parameters are estimated using regression
analysis. Activation energies, deactivation constants, and Arrenhius pre-exponential constants
are calculated with their respective confidence intervals. The lack of transport constrains of
