在有机化合物氧化、硝化,硝酸盐分解和硝酸制造等化工生产过程中,排放出一定量的氮氧化物(NO_x),形成了所谓“黄烟”污染大气,对工农业生产和人民健康产生危害,应当消除。用分子筛吸附法消除 NO_x,可将排放的 NO_x 回收成硝酸和增浓的 NO_x 循环回硝酸吸收系统,生成产品稀硝酸。分子筛吸附法的优点是:变废气为宝,消除污染且经济上较合理。本组合成的丝光沸石是以无定形硅铝物质为原
In the process of chemical production of organic compounds such as oxidation, nitration, nitrate decomposition and nitric acid production, a certain amount of nitrogen oxides (NO x) is emitted, forming the so-called “yellow smoke” polluting atmosphere, which harms industrial and agricultural production and people’s health. Should be eliminated. With molecular sieve adsorption method to eliminate NO_x, NO_x can be discharged back into nitric acid and concentrated NO_x recycled nitric acid absorption system to produce dilute nitric acid products. The advantages of molecular sieve adsorption method are as follows: changing waste gas to treasure, eliminating pollution and economically reasonable. Mordenite in this group is based on amorphous silicon-aluminum material for the original
