助剂对CuO/γ-Al_2O_3烟气脱硫活性影响的初步研究

Preliminary Study of the Effect of a Catalytic Promoter on the Activity of CuO/γ-Al_2O_3 for Flue Gas Desulfurization

燃烧等带来的SO2 、NOx 是酸雨的主要来源 ,采用可再生的CuO/γ Al2 O3作为脱除SO2 与NOx 的一体化吸附催化剂具有广阔的应用前景。本文通过在CuO/γ Al2 O3烟气脱硫剂中添加不同的金属盐化合物作为助剂 ,初步考察了各助剂对脱硫活性的影响 。

Sulfur dioxide and NO_x brought about by combustion processes are a main precursor of acid rain. The use of regenerative CuO/γ-Al_2O_3 as an integrated adsorption catalyst for the removal of sulfur dioxide and NO_x has wide prospects of applications. Through the adding of various metallic salt compounds into a CuO/γ-Al_2O_3 flue-gas desulfuriztion agent to serve as a catalytic promoter the effect of various promoters on desulfurization activation has been preliminarily investigated. In addition, with the help of physical characterization means an analysis was conducted of the internal causes, which enable these promoters to influence the desulfurization activation.
