Classifying Coal Blend on the Basis of IR Spectra and Multidimensional Analysis

The possibility of classifying coal in terms of IR spectra and soft independent modeling of class analogy (SIMCA) is considered. The samples investigated are first divided into two basic classes: optimal blend; and the alternative set of other blends. Spectral classification may be useful in identif...

Description
Summary:The possibility of classifying coal in terms of IR spectra and soft independent modeling of class analogy (SIMCA) is considered. The samples investigated are first divided into two basic classes: optimal blend; and the alternative set of other blends. Spectral classification may be useful in identifying the structural similarity of blends, so as to ensure stable coke quality.
