煤中灰成分催化指数的相关性

Interrelations of catalytic index of coal ash component

总结国内外不同方法的煤中灰成分催化指数定义的基础上,对10种配合煤进行了试验,探讨了不同方法的催化指数之间的相关性。结果表明,MBI,MCI,MMCI,MCIy四者之间的相关性良好,MBI和MCI之间相关性系数为0.9905,MCIy和MBI之间相关性系数为0.9821,MCIy和MCI之间相关性系数为0.9986。在一定程度上,四者可以互换。

According to summarizing different methods of defining catalytic index of ash component of coking coal at home and abroad,do experiments with ten kinds of blended coals,discuss the correlation among the various definitions of catalytic index.The results show that there is a good correlation among MBI,MCI,MMCI,MCIy.The correlation coefficient between MBI and MCI is 0.9905,MCIy and MBI is 0.9821,MCIy and MCI is 0.9986.To a certain degree,these four methods are interchangeable.
