Abstract
The present invention provides a method of estimating ingredients of liquefaction products of coal or its analogues from a resonance spectrum thereof obtained using their solid state,C nuclear magnetic resonance spectrometer. The method comprises the first step of obtaining a resonance spectrum of coal or its analogues using a solid state,C nuclear magnetic resonance spectrometer, the second step of determining distribution of various types of carbon having different linkage types which constitute the molecular structure of the coal or its analogues, and the third step of estimating ingredients of liquefaction products of the coal or its analogues on the basis of the determined carbon distribution.
