摘要

以污水污泥为原料，结合两种工业固体废弃物制备低浓度二氧化硫吸附剂。二氧化硫容量是根据实验室开发的突破性测试来测量的。采用均匀设计法确定了三种主要原料的不同配比，脱硫剂HN04以其最高的二氧化硫容量8.8 mg·g-1和最大的比表面积13.1771 m2·g-1为最佳吸附剂。研究了几种条件对吸附剂去除SO2性能的影响。结果表明，吸附剂HN04在SO2进口浓度5714 mg·m-3、空速2000h-1、蒸汽脱硫温度473K的最佳条件下，最大突破二氧化硫容量为9.7 mg·g-1。

Development and Application of a New Sulfur Dioxide Sorbent Based on Sewage Sludge

Sewage sludge-derived materials and two sorts of industrial solid waste were used to produce a sorbent for sulfur dioxide adsorption at low concentration. The sulfur dioxide capacity was measured according to a laboratory-developed breakthrough test. Uniform Design Method was used to formulate the different ratios of the three main raw materials and the desulfurizer HN04 was chosen as the optimal sorbent due to the highest sulfur dioxide capacity8.8 mg¡¤g-1 and the largest BET 13.1771 m2¡¤g -1. The effects of a few conditions on the SO2 removal behavior of the sorbent were studied. The results evince that the sorbent HN04 under the best conditions of 5714 mg¡¤m-3 inlet SO2 concentration, 2000h-1 space velocity and 473K desulfurization temperature in steam has the maximum breakthrough sulfur dioxide capacity 9.7 mg¡¤g-1.
