【摘要】 采用稀土型脱硫剂对模拟烟道气进行脱硫实验 ,考察了稀土含量、温度对脱硫效率的影响 ,并对脱硫剂进行了再生实验 .结果表明 :某些稀土化合物在较大的温度范围内对烟道气中SO2 有较高的吸附、催化转化作用 ,脱硫效率可达 90 %左右 ;脱硫剂可再生重复使用 ,再生操作简便易行更多还原

【Abstract】 The desulphurizing efficiency of artificial rare earth chimney gas desulphurizer and the effects of the content of rare earth and temperature were investigated. And the regenerating of the desulphurizer was carried out in laboratory. The result shows that some rare earth compounds have good adsorption and catalytic effects on the adsorption of sulphur dioxide in chimney gases, the primary desulphurizing efficiency can reach 90%, and the desulphurizing reagent can be re used conveniently.更多还原
