Abstract: 11 oxides (MgO, CaO, BaO, TiO2, V2O5, MnO2, Fe2O3, CuO, ZnO, PbO2 and B2O3), often found in coal-derived carbon materials, were loaded into the coal-derived carbon material by two methods such as adsorbing oxides through solution onto the surface of coke and adding oxides into the coal before carbonization. The effects of oxides on carbon solution reaction of carbon material were investigated and compared. The results show that the effect trends are similar but the effect of oxides by adsorbing is remarkably greater than that of the oxides by adding oxides as BaO, MgO, Fe2O3, CuO, ZnO, MnO2, PbO2 and B2O3. And the effect trends are similar. BaO, CaO and Fe2O3 are the greatest affecting oxides. The saturation point of addition content is 3% and that of adsorption is 1%.
