Distribution of contaminants used in automotive emission catalysts

Distribution of lead, zinc, iron, phosphorus, and sulfur in used automotive catalysts is determined by electron microscopy and the electron probe analyzer. Lead, phosphorus, and sulfur penetrate and coat the catalyst's washcoat micropore structure, thus accounting for their poisoning effect on...

Description
Summary:Distribution of lead, zinc, iron, phosphorus, and sulfur in used automotive catalysts is determined by electron microscopy and the electron probe analyzer. Lead, phosphorus, and sulfur penetrate and coat the catalyst's washcoat micropore structure, thus accounting for their poisoning effect on catalytic activity.
