Study on Metal Thermal Reduction of Caustic Calcined Dolomite Based Compound Desulfurizer

Abstract

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%.
