Constraints in the laboratory and the pilot plant often require deactivation by coking to be carried out by coke deposited from extraneous, fast-coking species especially added to the feed for that purpose. Questions which we attempt to answer are the following. Can the kinetics of coke deposition from the actual feed be estimated from a knowledge of the coke deposition rate during this accelerated coking process? How is the rate of reaction of the actual feed (as a function of coke level) changed by the presence of coke from the fast-coking species? What is the role played by reactions of the fast-coking species? Specific results for cumene cracking in the presence of dopants of varying ring sizes over a REHY zeolite are presented. A pulse microreactor with on-line integrated sample collection has been used for this purpose.
