Web1 INTRODUCTION. Coke formation in fluid catalytic cracking (FCC) can markedly affect a unit’s performance and for over fifty years, it has been the subject of much investigation. [1–3]. Coke can arise from a number of sources, namely acid catalysed, metals mediated and pure thermal reactions. WebOnce inside the reactor, the catalyst can mix with the feed uninhibited as a fluid. The feed then is cracked and while this occurs, the coke is deposited on the catalyst leading to the … WebJan 24, 2024 · The store will not work correctly in the case when cookies are disabled. ... Note 1: The size consistency (particle size distribution) of fluid petroleum coke is generally 100 % passing a 6.73 mm (No. 3) sieve and greater than 80 % passing a 2.00 mm (No. 10) sieve. Much of fluid cokes will pass a 0.59 mm (No. 30) sieve. grandview orthopedic clinic
