A series of zinc based desulfurizing agents doped with Mn and Cu have been prepared by coprecipitation with Na2CO3 as precipitant. The effects of the ratio (amount of substance) of Zn2+,Mn2+ and Cu2+ and calcinations temperature on desulfurization were tested by orthogonal experiment Using desulfurization effect of the desulfurizer as evaluation index. Sulfur capacity of the desulfurizer was tested by coulometric titration,and the desulfurizer was characterized by XRD. The results showed that,the different ...
