Coke is formed inside the pores and/or the external surface of solid catalysts, and is the primary cause of their deactivation (3). Therefore, it is essential to develop an understanding of all principal phenomena that govern catalytic cracking.Īll reactions of organic compounds on solid catalysts are accompanied by the formation of heavy by-products, the so-called coke, which is deposited on the surface of the catalyst and provoke deactivation (1,2). Without this understanding, advances in this field become increasingly rare and will be even more difficult to achieve in the future. A.A.Brillis., G.Manos., in Studies in Surface Science and Catalysis, 2001 1 INTRODUCTIONĬatalytic cracking of hydrocarbons has long reached technological maturity with only little benefit of a fundamental understanding and quantification of its elementary processes.
