AbstractBased on studies of controlling NOx from nitric acid exhaust gas domestic and abroad, this paper has developed a new technique on removal of NOx and production of a by-product with high added value-- MnO2. Experiment shows, pyrolusite, whose valid composition is MnO2, of absorbing NOx has the following characteristics: quick, low cost, no secondary pollutant. Moreover, exhaust gas can attain the required standards. If the temperature of the pyrolusite serum is 30℃, pH=4, containing 90 g/L MnO2, the absorptivity for 3 000 mg/m3 NOx is 89.2%. Furthermore,few of the impurities in pyrolusite dissolve in the absorption mother solution. The purification cost of product is very low.The purity of end product MnO2 is more than 99. 995% after purifying. Therefore, it is workable for the new technique on economy and technology. There are also obvious environmental benefits and marked economic returns.
