The results of a series of analyses of over 100 Rocky Mountain Province coals - selected from the Penn State Coal Sample Bank - by Curie-point pyrolysis mass spectrometry in combination with computerized pattern recognition techniques are discussed. The spectra obtained are shown to be quite representative for the coal seams with characteristic differences often present between different seams, fields or regions within the Rocky Mountain Coal province. In general, the spectra are found to be dominated by homologous ion series, e.g. representing dihydroxybenzenes, phenols, naphthalenes, benzenes, alkenes, dienes, alkyl fragments and sulfur compounds with varying degrees of aklyl substitution. The relative abundances of dihydroxybenzenes and naphthalenes are shown to correlate closely with differences in rank, whereas phenols, aliphatic hydrocarbons and sulfur compounds appear to correlate more closely with differences in depositional environment. Correlation between the pyrolysis MS data and a set of 25 conventional parameters obtained from the Penn State Coal Data Bank and including ultimate, proximate, petrographic and mineralogic measurements are investigated with the aid of computerized multivariate statistical analysis techniques. Strong correlations are found to exist between both data sets with regard to rank-related parameters and sulfur parameters as well as nitrogen content. The correlations found permit the calculation of numerical models which enable direct prediction of technologically important parameters such as rank, calorific value, and possibly, aromaticity from pyrolysis MS patterns.
