Abstract
As part of a study to analyze used catalysts, radiographs (x-rays) were taken of a number of used catalysts. Originally the radiographs were taken to aid in the disassembly of the catalysts. It was later found that the radiographs could be used to determine the amount of lead contained in the catalyst. The technique used to determine lead content is discussed and examples presented. Possible future uses of this technique in both research and after-market used catalyst screening are also discussed.
