ABSTRACT:
The invention describes a highly efficient catalytic pollution control process for removing N.sub.2 O from gaseous mixtures. The process utilizes catalysts derived from anionic clay minerals, which after appropriate heat activation, provide superior N.sub.2 O decomposition activity. The catalytic process comprises contacting an N.sub.2 O -containing gaseous mixture with the decomposition catalyst under conditions sufficient to convert the N.sub.2 O into gaseous nitrogen and gaseous oxygen. The process catalysts are derived from anionic clay materials such as the hydrotalcites, sjogrenites and pyroaurites.
