Pyrolysis-mass spectrometric prediction of liquefaction reactivity and structural analysis of coals

Forty-seven PSOC coals were pyrolyzed with eight replicates each in a Curie point pyrolysis mass spectrometer. This large data set was normalized and then analyzed using principal component analysis. From the reduced data set, equations were developed by using stepwise linear regression which modeled reactivity of the coal in tubing bombs and in the Gulf continuous flow reactor. Through the use of factor and loading spectra, structural components of the coal which were correlated with reactivity were identified. 33 references, 9 figures, 1 table.
