Method for simultaneous removal of nitrogen oxides from gases containing such oxides |
摘要 |
<p>The invention concerns a method for purifying flue gases before they are released into the atmosphere of their nitrogen oxides N<SUB>2</SUB>O and NO<SUB>x </SUB>by reaction with ammonia by causing them to circulate at temperatures between 200 and 600° C. on a catalyst based on beta-zeolite loaded with iron. The invention is particularly useful for treating tail gases from factories producing nitric acid.</p> |
