摘要/Abstract

摘要： 对几种常见金属氧化物的烟气脱硫（SO₂）进行了研究，分别从干法、湿法以及半干法详细介绍了常见金属氧化物的脱硫效果及影响脱硫效果的各种因素。干法脱硫剂主要发生吸附反应、氧化反应；湿法脱硫主要是液相催化氧化作用；半干法脱硫以CaO为主要脱硫成分。干法脱硫催化剂有再生操作复杂、制备成本较高的缺点；湿法烟气脱硫效率高、适应范围广，成为主要的烟气脱硫方法，但湿法脱硫也存在占地面积大、技术复杂、脱硫过程中会造成资源浪费等问题。本文对比总结了常见金属氧化物的脱硫特点及其工业应用现状，分析了矿浆脱硫的可行性，同时对矿浆脱硫的研究前景提出展望，从而进一步为工业废气净化研究奠定基础。

Abstract: In this paper,the desulfurization effect of several common flue gas desulfurization metal oxides(SO₂) and the influence factors were studied,from the aspects of dry,wet and semi-dry desulfurization factors in detail. Dry desulfurization mainly includes adsorption reaction and oxidation reaction,while wet desulfurization mainly has liquid phase catalytic oxidation,and the main components of desulfurization of semi-dry desulfurization is calcium oxide. Dry desulfurization catalyst has the disadvantages of complex regeneration operation and high preparation cost,while wet flue gas desulfurization technology has high desulfurization efficiency,and wide range applications,which makes it a major method of flue gas desulfurization. However,wet desulfurization also requires large space,and complicated technology,and has the resource wastes and other issues. In this paper,we also compare and summarize the common metal oxide desulfurization characteristics and industrial application situation,analyze the feasibility of pulp desulfurization. The prospects of pulp desulfurization research,which provide a foundation for the research of industrial waste gas purification.

Key words: metal oxide, flue gas desulfurization, catalyst support, catalysis, oxidation
