Co-Hydrogenation Performance of Pine Sawdust and Heavy Components of Coal Tar Wang Li, Wei Wang, Wen-ying Li*



Making the heavier components of coal tar into lighter components, which are the raw material for fuel and the chemicals, will improve the economy of pyrolysis. To promote the hydrogenation of heavy components, the co-hydrogenation of heavy components and pine sawdust (PS) was extensively studied in this work. The addition of PS significantly promoted the hydrogenation of heavy components which improved the yield of n-hexane soluble matter from 66.63 wt% to 75.46 wt%. The results of synchronous fluorescence showed that the product has a significant degree of lightening. Addition of biomass increased the aliphatic hydrogen content as evidenced by Fourier transform infrared spectroscopy.
