This coal, of Cretaceous age and from southwest Utah, attracted attention because a lithobody from it showed a high hydrogen content and excellent behavior in liquefaction. The seam is 230 cm thick and consists of an upper and lower lithobody of a cl

Measurements of aliphatic C–H content by FT-i.r. have been correlated to the plastic properties and liquefaction behaviour of a set of coals and vitrinite concentrates obtained from the Lower Kittaning seam. It has been found that for vitrinites a

The problems associated with the application of FT-IR to the characterization of coal structure are critically discussed. The controversies concerning band assignments are considered and it is concluded that the strong 1600 cm−1 band can be assigne

Magic-angle 13 C n.m.r. spectra have been obtained for a series of vitrinite concentrates. Proper modification of the cross-polarization pulse sequence allows separation of protonated and nonprotonated carbon resonances. This technique is used to det

The fraction aromaticity determined by 13 C n.m.r. with cross-polarization and magic-angle spinning of 19 vitrinite concentrates obtained from the Lower Kittaning seam shows a range of values from ≈ 0.65 for the samples of lowest rank (83 wt% C (dm
