摘要 对以软锰矿作催化剂、水为吸收剂、用鼓泡塔半连续吸收烟气中低浓度的 SO2 并副产稀硫酸的工艺进行了可行性研究 ,考察了矿用量、停留时间、进口 SO2 浓度、吸收液初温等因素对脱硫制酸的影响 。 A process for removal of SO 2 from flue gas and then accessory production of dilute sulfuric acid by aqueous pyrolusite catalyzed oxidation was studied in absorption tower in the semi continuous operation condition.The effects of the ratio of pyrolusite to water,stay time,inlet concentration of SO 2,temperature,etc.on desulfurization and production of dilute sulfuric acid were investigated.The results provided the theoretical basis for industrial use of aqueous suspension of pyrolusite in flue gas desulfurization then producing dilute sulfuric acid.
