A total of 69 samples have been obtained from the Lower Kittanning seam in western Pennyslvania and eastern Ohio. The samples were taken from 39 sample sites and consist of 39 channel samples and 30 hand-picked vitrinites. A complex statistical analysis of petrographic, physical and chemical properties of these samples was performed in order to study their relationship with thermoplastic and liquefaction behavior. The parameters of the thermoplastic properties were obtained using a Gieseler plastometer. The liquefaction conversion with tetralin was determined in tubing bomb reactors at 400/sup 0/C for 1 hour. Factor analysis on the whole sample population indicated that both liquefaction conversion and some of the measured thermoplastic properties are significantly related with rank. Temperature of softening and degree of fluidity, however, did not load on the rank component. /sup 13/C nmr spectra were obtained for six of our vitrinite concentrates by the University of Utah. The aromaticities determined for fairly wide rank range of these samples varied only from 0.66 to 0.72. However the series showed progression from highly functional aromatic structure at low rank to one with little functionality at high rank. The spectra show no indication of a consistent loss in aliphatic oxygen. The surface areas and micropore volumes of two fractions, -20 and -100 mesh, of five vitrinite concentrates have been measured from CO/sub 2/ uptake at 25/sup 0/C. An increase in these values is observed with decreasing particle size. Total open pore volumes were calculated from particle and helium densities.
