摘要
Abstract
V2O5-WO3/TiCX catalyst was prepared by dipping method. The effects of the contents of WO3 and V2O5 on the denitrating activity of the catalyst were studied. The effects of composite carrier on the catalyst property were also studied by adding SiO2 or Al2 O, powders into the catalyst carrier. The experimental results show that: The suitable mass fractions of WO3 and V2O5 are 10% and 0.05% respectively; The addition of SiO2 or Al2 O3 powders will result in some reduction of the catalyst denitrating activity, but can enhance its mechanical strength, extend its useful life and increase its reusing times.关键词
