Therefore, it must be purified to avoid catalyst poisoning ( i . e . : destroying catalytic activity and loss of efficiency ).
2.
Depending on the contaminant, catalyst poisoning can sometimes be reversed by running the engine under a very heavy load for an extended period of time.

Presuming you've made the mistake of using leaded fuel in a car with a catalytic converter, our article mentions " Depending on the contaminant, catalyst poisoning can sometimes be reversed by running the engine under a very heavy load for an extended period of time.
4.
They utilized organometallic compounds dissolved in a volatile solvent like benzene that would yield a mixture of ultrafine catalyst particles ( 5 25 nm in diameter ) in hydrocarbon gas as the temperature rose to 1100 �C . In the furnace, the fiber growth initiates on the surface of the catalyst particles and continues until catalyst poisoning occurs by impurities in the system.
