PURPOSE:To enhance desulfurizing activity and the performance as a dust removing filter medium by manufacturing a desulfurizing and dust removing agent mainly composed of iron oxide of 10-90wt.%, aluminum oxide of 90-10wt.% and silicon oxide. CONSTITUTION:Iron oxide powder or natural iron ore powder mainly composed of iron oxide as an active substance to desulfurizing reaction, aluminum oxide powder as a strength developing material and silicon oxide powder are mixed together. Said mixture is granulated, and then said granulated material is dried and then fired to manufacture a desulfurizing and dust removing agent. The desulfurizing and dust removing agent thus manufactured is composed mainly of iron oxide of 10-90wt.%, aluminum oxide of 90-10wt.% and silicon oxide. The suitable grain diameter of said granulated material is in the range of 1/10-8mm and the suitable firing temperature is in the range of 800-1400 deg.C. |
