自蔓延高温燃烧合成法制备CeWTiOx催化剂及其NH3-SCR性能OA北大核心CSCDCSTPCD
Preparation of CeWTiOx catalysts via self-propagating high temperature synthesis and its NH3-SCR performance
采用自蔓延高温燃烧合成法制备了CeWTiOx系列催化剂并考察了其氨选择性催化还原NOx(NH3-SCR)性能.利用X射线衍射、N2吸附-脱附、H2程序升温还原、X射线光电子能谱、NH3程序升温脱附表征和分析了催化剂晶相、结构、氧化还原能力和酸性强度与其活性之间的关系.结果表明,Ce40W10TiOx催化剂在150-430℃NO转化率可达80％以上,含硫条件下200℃NO转化率可保持在97％左右.结果表明,该催化剂的低温活性和抗硫性能主要与W的掺杂…查看全部>>
A series of CeWTiOx catalysts were prepared by self-propagating high-temperature synthesis method,and their NH3-SCR activities were evaluated.X-ray diffraction,N2 adsorption-desorption,H2-temperatureprogrammed reduction,X-ray photoelectron spectroscopy and NH3-temperature-programmed desorption were performed to investigate the relationship between the catalyst activity and its physicochemical properties such as crystalline phase,specific surface area,r…查看全部>>
