13C high resolution solid state NMR spectra of Chinese coals

Several typical exinites in China including alginite, cultinite, suberinite and bituminite are analysed by means of¹³C high solution solid state CP MAS TOSS NMR spectra to determine their chemical structures and hydrocarbon potential. Thermal simulation solid products (TSSP) of hydrogen-rich coals are studied to discuss the generation and expulsion mechanism of coal-generating hydrocarbon. The preliminary results are quite encouraging, wntaining useful information about genesis of coal-generating oil and gases.
