摘　　要：文章选取CaCO3、Ca(OH)2质量配比=3∶2作为主固硫剂,用2%钙基(质量配比)的Na2CO3对其改性,利用蛭石作为固硫添加剂。在Ca/S=2.25的情况下通过固硫实验考察了主固硫剂以及添加剂的加入对固硫率的影响。实验表明:煤粉掺入该固硫剂在950℃下燃烧半小时,固硫率可以达到85%,该固硫剂主要由天然矿物所组成,具有来源广、成本低廉等优势,因而具有极高的应用价值和市场推广潜力。Ca（OH）2 and CaCO3 were selected as the main sulfur-fixed agent,their mass ratio was 2∶3.Vermiculite and Na2CO3 were selected as the additives.The influence on the desulphurization ratio by the addition of main sulfur-fixed agent and additives were studied under Ca/S=2.25.Result showed that the desulphurization ratio of powder coal with the addition of sulfur-fixed agent could achieve 85 % at 950 ℃ and burning half an hou r.Being composed of natural minerals,the sulfur-fixed agent had special characters with lower capital cost higher practical value and broader marketing potentiality.
