Abstract
A study on the catalytic cracking of cumene using a novel CREC Riser Simulator was carried out using two sizes of zeolite crystals. The catalytic cracking of cumene is a model compound allowing to test FCC catalyst under conditions free of intra-crystalline diffusional constraint with the effectiveness factor remaining very close to unity. A novel catalytic activity decay model based on "reactant conversion", which allowed defining the changes of chemical species without the specific extra requirement of measuring the coke concentration was presented. Kinetic and activity decay parameters were estimated for the model utilizing regression analysis, with parameters established with their respective confidence intervals. The consistency of the kinetic parameters for the two-zeolite crystals was an encouraging result to support the validity of the proposed model.
