Question

The catalyst deactivation caused by deposition on surface and pores of catalyst is called ____

(a) Adsorption

(b) Regeneration

(c) Fouling

(d) Desorption

I had been asked this question by my school teacher while I was bunking the class.

My question is taken from Mechanisms of Catalyst Deactivation topic in division Suspended Solid Reactors, Catalyst Deactivation, Diffusion and Reaction of Chemical Reaction Engineering

Answer 1

The correct option is (c) Fouling

For explanation I would say: Fouling is caused by the blockage of pores on the catalyst. The life and the efficiency of the catalyst is reduced by fouling.
