摘要
用液相催化氧化SO_2的方法净化吸收低浓度SO_2废气,并生成复合硫酸铵盐所得产品中含有多种作物营养元素,能够作为一种新型多效复肥使用,复肥中的作物营养素在SO_2液相催化氧化过程中起到了催化剂作用.
The removal of SO_2 from waste gases by mesns of catalytic oxidation of SO_2 in aqueous solution to produce complex fertilizer is investigated in this paper. The ammonium sulfate obtained in the experiment contains several kinds of nutriment needed by rops; it can be used as a new complex fertilizer. The nutriment contained in the complex fertilizer as a kind of catalyst has a catalytic effect on the oxidation of SO_2 in aqueous solution.
