How Can Catalyst Deactivation Affect Product Quality?
Catalyst deactivation can significantly reduce the efficiency of a catalytic process. For instance, poisoning by impurities such as sulfur or lead can irreversibly bind to the active sites of the catalyst, rendering it less effective. Fouling can occur when by-products deposit on the catalyst surface, blocking active sites. Sintering involves the aggregation of catalyst particles at high temperatures, reducing the surface area available for the reaction. Finally, coking refers to the deposition of carbonaceous materials which can block the pores of the catalyst.
