When a catalyst loses its activity, it is called catalyst poisoning. If recovery is possible quickly, it is called temporary poisoning; if recovery is not possible, it is called permanent poisoning.
Catalyst poisoning refers to the phenomenon in which a catalyst experiences a significant reduction or loss of its catalytic activity and selectivity due to the effect of certain trace impurities. These substances are called poisons. Toxins are usually impurities introduced from the reaction materials, or certain impurities present in the catalyst itself; reaction products or by-products can also poison the catalyst.

Catalyst poisoning – the phenomenon in which trace impurities present in the reaction feedstock cause a significant decrease or loss of the catalyst’s activity and selectivity.

The phenomenon in which trace impurities present in the reaction materials cause a significant decrease or loss of the catalyst’s activity and selectivity. The essence of poisoning is a certain chemical reaction between trace impurities and the active centers of the catalyst, resulting in the formation of inactive species. Adsorption complexes are formed in gas-solid multiphase catalytic reactions. One type is when the toxin has a weak effect on the active component, and the activity can be restored using simple methods; this is known as reversible poisoning or temporary poisoning. Another type is irreversible poisoning, for which it is impossible to restore activity using simple methods. To reduce the activity of side reactions, it is sometimes necessary to selectively poison the catalyst.

The catalyst becomes deactivated as a result of chemical reactions.
