Abstract: The efficiency of sulfur capture of CaO, Ca(OH)2 and CaCO3 as well as the effect of CuO on them were studied. Results showed that the efficiency of sulfur capture of Ca(OH)2 is the highest among these three compounds. When CuO was used with each of CaO, Ca(OH)2 and CaCO3 at the same time, the efficiency of all of them would rise, and that of Ca(OH)2 raise most. The efficiency of sulfur capture of Ca(OH)2 with CuO is 14.4% higher than that without CuO.

Keywords: CuO, Ca(OH)2, sulfur capture
