| 英文摘要 | Zinc and lead-bearing metallurgical dust (ZLMD) exhibit strong desulfuration ability due to their higher content of metal oxides, such as Fe2O3, ZnO, PbO and CaO. In present work, their performances as a sulfur absorbent used in the combustion process of briquette, which is made up of coal and ZLMD, are investigated. Experimental results show that a large part of H2S and a small part of COS, CS2are volatilized from briquette and react with ZnO and PbO to form ZnS and PbS at the earlier stage of combustion, and that O2oxidizes FeS2to form SO2at the later stage. The adsorption reaction of sulfur depends on the content of CaO. ZnO, ZnS and CaSO4are stable during the combustion process at temperatures lower than 1100掳C. When the weight percent of ZLMD in the briquette is kept at around 2.5%, and sulfur in coal at around 2.1%, the absorption efficiency of sulfur can reach 90%. These results suggest that utilizing ZLMD as a sulfur absorbent in the combustion process of briquette is a cheap and highly efficient method to treat both ZLMD and toxic emission such as H2S/SO2released during briquette combustion processes. 漏 2004 Published by Elsevier Ltd. |
