Abstract

The chemical structure of Yunan sphugnum brown coal and its solid state thermo-simulated products atvanous temperatures were investigated by the newest developed solid state high resdution NMR techniques(i.e，¹H CRAMPS Spectrum, ¹H spin-Lattice relaxation time T₁and ¹H homo-nuclear Bipolar dephasingdecay constant Too, ¹³C CPMAS spectrum, ¹³C spin-lattice relaxation time T₁and,¹³C hetero-nucleardepolar dephasing decay constant T_DDThe results clearly reveal the mechanism of generation and expul-sion of gaseous and liquid hydrocarbons during the thermo-simulating process of Yunan sphugnum Brown coal
