Abstract：In order to verify the mechanism and the feasibility of the mild hydro-upgrading technology, the experiment with the Naomaohu coal in Xinjiang was performed by using autoclave, tetralin, and the nano iron based catalyst.Compared with the raw coal, the coking index of the product was up to 90, the ash, total sulfur and the hydrogen content were increased, the oxygen content was reduced.The test result showed the effect of hydro-upgrading was better.The hydrogenation products were analyzed by 1 3 C-NMR.The number of condensed rings had been increased, the number of the bridge bond and the aromatic rings had been reduced, the average molecular weight and the number of condensed ring had been increased, and the degree of aromatization had been strengthened.According to the molecular structure parameters, the molecular structure model had been simulated.The coal blending test showed that the hydrogenation product could be used to coal blending and coking. The technical route would lay the foundation for the process application of hydro-upgrading.
