Question

Carbon atoms stick to catalyst surface in craking processes ?

1- sintring
2- poising
3- aging
4- cocking or fouling

Answer 1

option D - coking or fouling

Step-by-step explanation:

Coking (not cocking) is the process involving the deposition of small carbon particles (created by simply putting carbon atoms) on a catalyst's accessible surface, leading in a reduction in the area accessible for catalytic activity. This is also sometimes related to fouling catalysts or merely fouling them.
