| 摘要 |
The present invention relates to a process and apparatus for non-destructive identification of encased autocatalysts which comprise metallic and/or ceramic support substrates which may possess a catalytic coating. The process comprises the X-raying of the encased autocatalysts and the identification of the autocatalyst by comparing the data obtained with a data bank which contains information about industrially manufactured autocatalysts. Optionally, the process may comprise further examination steps (for example weighing, measurement of the electrical and/or magnetic properties or photographic imaging). The process and apparatus find use for non-destructive, exact and rapid recognition or identification of encased autocatalysts and particulate filters.
