摘要
ＢａＣＯ３、Ｓｒ（ＮＯ３）２是水泥窑用高硫煤的较好脱硫剂，同时它们对高硫煤的燃烧也起到了较好的催化作用。利用差热分析及燃烧率测定，研究了ＢａＣＯ３、Ｓｒ（ＮＯ３）２以及它们共存或与ＣａＣＯ３共存时，对高硫煤的燃烧催化程度，进而讨论了催化机理。
BaCO 3、Sr(NO 3) 2 are better desulphurizers using in the cement kiln,and at the same time,they can catalysed the combusition of high sulfur coal. This paper studies the catalyse extent of BaCO 3、Sr(NO 3) 2、BaCO 3+CaCO 3、Sr(NO 3) 2+CaCO 3、and Sr(NO 3) 2+BaCO 3 by DTA and combusitibility analysis,and discussed the mechanism of catalysed.
