Taken caustic calcined dolomite based compound desulfurizer as the research object, influence of fluxing agent CaF2, Al2O3, SiO2 and heating agent on the melting temperature of the compound desulfurizer was mainly investigated during its directly reducing process. Fluxing agent SiO2 and heating agent are the main influence factors, which influence melting temperature of the compound desulfurizer, the next are CaF2 and Al2O3. The mean value of compound desulfurizer melting temperature is respectively 1190.3°C and 1199Subscript text.1°C when the addition amount of SiO2 and heating agent is respectively 8.33% and 33.55%. With the increase of CaF2, the mean value of compound desulfurizer melting temperature decreases gradually, however, which increases first and then decreases with the increase of Al2O3.The conditions of the lowest melting temperature about the compound desulfurizer is A4, B1, C1, D2, namely 9% CaF2 + 0% Al2O3 + 8.33% SiO2 + 33.55% heating agent.
Caustic calcined dolomite based compound desulfurizer by the aluminum thermal reduction was taken as study object. Effect of fluxing agent, reaction time and experimental temperature on the weightlessness of compound desulfurizer was studied. The result showed that the weightlessness of compound desulfurizer decreases slightly with the increase of fluxing agent CaF2 content. When the content of SiO2 changes from 12% to 20%, the weightlessness of compound desulfurizer which is basically about 27.5% changes a little. With the increase of experimental temperature and reaction time, the weightlessness of compound desulfurizer is gradually increased. When the reaction time and temperature is respectively 20min and 1300°C, the weightlessness of compound desulfurizer is 31.80%.
