N2 - The role of carbonaceous overlayers (or coke), and the influence of different reaction pathways on how they are deposited were studied. Ethylbenzene dehydrogenation was used as a model system. The catalytic features that lead to carbon build-up were analyzed. Different regimes were observed at different times-on-stream, i.e., a cracking period (high selectivity to benzene and toluene) and styrene breakthrough after ∼ 3 hr. Most of the carbon deposited in the reaction occurred at reaction times < 3 hr, indicating that it arises due to the cracking reaction. A direct correlation between catalyst performance and the structural characterization of coke was observed. This is an abstract of a paper presented at the 22nd Annual Saudi-Japan Symposium on Catalysts in Petroleum Refining and Petrochemicals 2012 (Dhahran, Saudi Arabia 11/25-26/2012).
