Study On The Characteristics And Mechanism Of CuO-three-Dimensional Carbon Nanotube Composites For H₂S Removal

Many industrial exhaust gases contain hydrogen sulfide,which not only corrodes pipes and damages equipment,but also requires high precision and desulfurization conditions to remave hydrogen sulfide,T herrfore.from the consideration of safety,environment,economy and other factors,the development of new types,practical and flexible,High-precision deailfunzation agent has praclical significance.A large amount of oxygen vacancies and defects are produced on the surface of the rono-copper oxide,which greatly improves the sulfur capacity and reactivity of the nano-copper oxide desulfurization agene.The copper oxide was loaded on the carbon nanotubes by the dippingmethod to prepare nano-copper oxide crystals with an average particle size of 14.2nm,and various technical means were used to characterize the pupped dcsulfurizing agent and study its surface morphology.composition and particle size.Diameter,shape,surface strueture,elecuonic price and other characteristics.The desulfurization agent prepared was studied under the experimental conditions of 300?,and the influence of oxygen,carbon monoxide,and carbon dioxide atmosphere on the desulfurization conditions such as the intake air rale,the initial concentration of hydrogen sulfide,and the experimental temperature were investigated.In this case,the conversion rale of the desulfurizer exceeds 40%.The optimal gas velocity is 0.065m/s.On the urfacc of product analyst,the mechanism of removing H2S is as followse first,after the H2S molecule is adsorbed with the CuO desulfurintion agent,it reacts under suitable conditions to generate water and CuS solids.In this process,to remove H2S,good adsorption and chemical reaction are two important ways to remove H2S.According to the experimental data,knk-1/T is plotted,and the kinetic equation is was(r)=55547.845exol-155.11194/R7).activation energy Ea is:155.11194 kJ/mol,and the pre-finger factor is 55547.145.Studies have shown that CuO-three-dimensional carbon nanotube desulfurization agent has good industrial British prospects.
