Na, Co{sup 2+}, Ce{sup 3+}, and Co{sup 2+}Ce{sup 3+} exchanged A type zeolite have been tested for NO and N{sub 2}O adsorption and decomposition at room temperature. Dynamic temperature programmed desorption (TPD) studies were also carried out with these four zeolites, as well as with CeO{sub 2} and CoA zeolite mixed with CeO{sub 2}. It was demonstrated that NO was especially decomposed into N{sub 2}, with some N{sub 2}, with some N{sub 2}O, over the doubly ion exchanged CoCeA zeolite that contained 1.77 Co and 2 Ce per unit cell. Some segregation of CeO{sub 2} occurred during these experiments, and a lower content of Ce in the CoCeA zeolite might be utilizable.
