Description
Summary:	Scientists developed a thioresistant NO sub(x) trap that utilized CuO supported on sulfated zirconia mixed with a solid base. Data are reported detailing the rate of adsorption of NO at constant temperature and the quantity of NO retained from a feed that contained 750 ppm NO, 10% O sub(2), and 5% water in nitrogen. Tests conducted for poorly dispersed CuO indicated that the capacity for NO sub(x) adsorption does not decrease, although it increases slightly in the presence of 25 ppm SO sub(2) in the feed. Irreversible poisoning was observed for a well-dispersed Cu catalyst. Decomposition of surface nitrates was achieved at a temperature of 623 K. Researchers concluded that the catalyst does not lose any adsorption capacity following 10 cycles of adsorption-desorption.
