Coke on catalyst
WebMar 20, 2024 · Pore blockage due to coke formation is a very common problem in zeolites catalysis. This restricts access of reactant molecules to the catalyst active sites [ 3, 4 ]. The strength of the acid sites and higher acidity are among the main factors that determine the severity of coke formation [ 4, 5 ]. WebCoking is characteristic of high temperature reactions involving hydrocarbon feedstocks. Typically coking is reversed by combustion, provided that the catalyst will tolerate such. [2] [better source needed] A simplified equation for coking is shown in the case of ethylene : 3 C 2 H 4 → 2 C ("coke") + 2 C 2 H 6
