Ethylbenzene dehydrogenation was used to study coke deposition. The majority of coke was found to be deposited during a cracking induction period that could be prevented by pre-coking with various precursors. Offline analysis showed the nature of coke to be highly dependent upon reaction temperature, time on stream and precursor.
