SCAVENGER AND LEAD POISONING OF AUTOMOTIVE OXIDATION CATALYSTS
The deactivation of noble metal oxidation catalysts of lead and halide lead scavengers was studied in engine and laboratory experiments. Lead alone or lead plus scavengers produced a persistent poisoning of the catalyst. Lead poisoning effects were increased by increased catalyst temperatures and fuel lead content. Tests with scavengers only, conducted in an engine previously operated on leaded fuel, showed that lead was transported to the catalyst causing lead poisoning even in the absence of lead in the fuel. These experiments showed that the reversible scavenger inhibition effects could be superimposed on the persistent lead poisoning effects.
