主　　题：ACF H_(2)S PH_(3) Cu Low temperature Simultaneous removal 

摘      要：Poisonous gases,such as H_(2)S and PH3,produced by industrial production harm humans and damage the *** this study,H_(2)S and PH3 were simultaneously removed at low temperature by modified activated carbon fiber(ACF)*** have considered the active metal type,content,precursor,calcination,and reaction *** results exhibited that ACF could best perform by loading 15%Cu from *** optimized calcination temperature and reaction temperature separately were 550℃ and 90℃.Under these conditions,the most removal capacity could reach 69.7 mg/g and 132.1 mg/g,*** results showed that moderate calcination temperature(550℃)is suitable for the formation of the copper element on the surface of ACF,lower or higher temperature will generate more cuprous *** both can exhibit catalytic activity,the role of the copper element is significantly *** to the exceptional dispersibility of copper(oxide),the ACF can still maintain the advantages of larger specific surface area and pore volume after loading copper,which is the main reason for better performance of related ***,increasing the copper loading amount can significantly increase the crystallinity and particle size of copper(oxide)on the ACF,thereby improving its catalytic *** situ IR found that the reason for the deactivation of the catalyst should be the accumulation of generated H_(2)PO_(4)^(-) and S0_(4)^(2-)(H_(2)0)^(6) which could poison the catalyst.
