Experimental Study on Effect of Electrolytic Temperature on Performance of ZnO/semi Coke Desulfurizer

The active semi char loaded with Zinc Oxide was prepared by electrochemical deposition with a semi coke as the carrier,zinc nitrate（Zn（NO₃）₂） and six times methyl four amine（ HMT） as the electrolyte.The samples were characterized by SEM,TEM and FT-IR,and the effects of different electrolysis temperatures on Zn O/char compound desulfurizer were investigated,and the SO₂ adsorption properties of Zn O/char Desulfurizer at different electrolysis temperatures were evaluated.The results show that,under reaction conditions of 60 min electrolytic time,80 ℃ electrolysis temperature,3 V electrolytic voltage,0.001 5 mol/L Zn²⁺ and 0.001 5 mol/L HMT,the prepared catalyst has the 360 min penetration time and 6.1 g sulfur capacity,which can achieve the best load effect and desulfurization effect.
