针对目前化工行业酸性气体（H2S）和杂质污染物排放的问题，提出以催化燃烧代替传统高温燃烧法来处理酸性气体及杂质污染物的新思想。项目通过调控不同的元素组成和多功能活性相的构建，合成六铝酸盐催化剂（高温催化材料），系统地研究酸性气体（H2S）和杂质污染物（NH3, HC）在六铝酸盐催化材料上的吸附、活化、活性氧种、反应中间物种和副产物、反应过程与机理和多组分动力学规律。.项目目的在于研究得到具有良好催化性能的铝酸盐催化材料、污染物消除的反应机理和多组分动力学规律，形成高效的催化氧化(包含部分选择氧化)技术，结合后处理工艺，为我国化工行业酸性气体（H2S）控制与利用提供科学技术基础。丰富人们在酸性气体污染控制和高温催化材料方面的科学认识。

Based on the pollution emissions of acid gas (H2S) and impurities pollutants (NH3, HC) from chemical industries, the catalytic oxidation of acid gas and impurity pollutants is proposed to replace high-temperature combustion.Various Hexaaluminate (HA) catalysts are rationally designed and synthesized with different composition and structure.The adsorption, activation, active oxygen species, intermediate species, by-products, reaction processes and mechanism of catalytic oxidation of acid gas (H2S) and impurity pollutants (NH3, HC) and multicomponent kinetics are comprehensively investigated and studied over these HA catalysts. . It aims to obtain HA catalysts with high catalytic activity and excellent durability, clarify the catalytic reaction mechanism and multicomponent kinetics, develop efficient catalytic oxidation (including partial selective catalytic oxidation) technology. Finally, it can provide scientific and technical support for the catalytic combustion of H2S and impurities in industry, contribute our knowledge to high-temperature catalytic materials and acid gas pollution control.
