摘　　要：本文在有石灰存在情况下,用褐煤作还原剂,对攀枝花钛铁矿回转窑还原脱硫过程进行了研究。结果表明脱硫反应是在气固相界面之间进行,气体COS是中间载硫体。经分选后,还原产品含硫小于0.05%。The reduction and desulfurization of Panzihua ilmenite in one process have been studied in the presence of lime. The lignite was used as reductant. The tests were performed in a rotary kiln.The results showed that the desulfurization reaction took place at gas-solid interfaces, and that gaseous COS was found to be an intermediate product acting as sulfur-carrier. After separation the sulfur content in reduction product was less than 0.05Pct.
