摘要:

用CuO/Al2O3脱硫吸附剂对燃煤电厂进行烟气干法脱硫是一种先进的脱硫技术.考察了脱硫剂CuO在载体的分散状态、焙烧温度对Al2O3吸附剂载体结构的影响、脱硫剂制备时要考虑的问题、脱硫反应的温度等因素对吸附剂脱硫效果的影响.实验证明:CuO在Al2O3载体上是单层分散的;焙烧温度过高会使载体烧结、脱硫活性下降,脱硫吸附剂必须用还原气体进行再生;要用Cu(NO3)2溶液做浸渍液,用等体积浸渍法制备脱硫剂;在400～430℃之间进行脱硫反应是最合适的.在合理的条件下,得到了良好的脱硫效果.

Abstract:

The flue gas dry desulfurization of coal-fired power plants with CuO/Al2O3 desulfurization adsorbent is an advanced desulfurization technology. The dispersion state of the desulfurizer CuO in the carrier, the influence of roasting temperature on the structure of Al2O3 adsorbent carrier, the problems to be considered in the preparation of desulfurizer, the temperature of the desulfurization reaction and other factors on the desulfurization effect of the adsorbent were investigated. Experiments show that CuO is monolayer dispersed on Al2O3 carrier. If the roasting temperature is too high, the sintering and desulfurization activities of the carrier will decrease, and the desulfurization adsorbent must be regenerated with reducing gas; Cu(NO3)2 solution should be used as impregnation solution, and desulfurizer should be prepared by equal volume impregnation method; It is most suitable to carry out the desulfurization reaction between 400~430 °C. Under reasonable conditions, a good desulfurization effect is obtained.
