| Abstract: | The different preparation conditions of four catalysts and its effect on extracting humic acid from weathered coal were investigated in this paper. The results showed that SO4^2-/Fe2O3, SO4^2-/FeV, AC/Fe2O3 and AC/V2O5 all had some catalysis, and the best one was AC/V2O5 catalyst. Compared to the control without catalyst, humic acid yield catalyzed by AC/V2O5 was improved by 10.2%. The preparation conditions ofAC/V2O5 catalyst were that the ratio of AC and oxalate oxovanadium solution was 1.5 ： 1, and the roasting temperature was 500 ℃. |
