14. Effects of Reaction Conditions on the Hydrogenolysis Reactions of Cation Exchanged Coals

Abstract

The effects of the reaction conditions on the hydrogenolysis reaction of cation (Co^<2+> or Ni^<2+>) exchanged Adaro coal in tetralin solvent with sulfur promoter were discussed. In comparison with the reactions of the demineralized coal with metalocene complex [(C_5H_5)_2Co,(C_5H_5)_2Ni] at 400℃-440℃, the conversion of acetone insoluble constituent in coal increased on those of cation exchanged coals. On the reaction of the demineralized coal with cation exchanged one, the upgrading of demineralized coal was also enhanced by the catalytic effect of cation in cation exchanged coal.
