Embodiment 1
[0036] The ash content is 21%, the aluminum oxide content in the ash is 25%, and the high ash content anthracite of silicon oxide content is 50% is crushed to below 40 meshes, then weighs 20g of the high ash content anthracite after crushing, and puts it into poly In the vinyl fluoride reactor, then add the hydrofluoric acid of 200ml 1mol / L and the hypochlorous acid of 40ml 1mol / L in the polytetrafluoroethylene reactor, to form the first mixture, at room temperature (20 ℃) for the first The mixture was stirred for 1 h. Then, the first mixture is subjected to solid-liquid separation, and the solid obtained from the solid-liquid separation is pretreated high-ash anthracite. After measurement, the ash content in the pretreated high ash anthracite is 14%, the alumina content in the ash is 13.7%, the silicon oxide content in the ash is 27.5%, and the content of oxygen-containing functional groups in the pretreated high ash anthracite is 8.3 %. After calculation, the removal rat...
Embodiment 2
[0043] The ash content is 30%, the alumina content in the ash is 40%, the high ash content anthracite coal that the silicon oxide content is 30% is crushed to below 40 meshes, then weighs 20g of the crushed high ash content anthracite, and puts it into poly In the vinyl fluoride reactor, then add 300ml of 3mol / L tetrafluoroboric acid and 80ml of 5mol / L sodium hypochlorite aqueous solution to the polytetrafluoroethylene reactor to form the first mixture. Then the first mixture was heated so that the temperature of the heated first mixture was 40° C., and the first mixture was stirred for 2 hours. Then, the first mixture is subjected to solid-liquid separation, and the solid obtained from the solid-liquid separation is pretreated high-ash anthracite. After measurement, the ash content in the pretreated high ash anthracite is 10%, the alumina content in the ash is 35.4%, the silicon oxide content in the ash is 17.6%, and the content of oxygen-containing functional groups in the p...
Embodiment 3
[0055]The ash content is 21%, the aluminum oxide content in the ash is 25%, and the high ash content anthracite of silicon oxide content is 50% is crushed to below 40 meshes, then weighs 20g of the high ash content anthracite after crushing, and puts it into poly In the vinyl fluoride reactor, 250ml of 2mol / L hydrofluoric acid and 60ml of 4mol / L hypochlorous acid were then added to the polytetrafluoroethylene reactor to form a first mixture. Then the first mixture was heated so that the temperature of the heated first mixture was 50° C., and the first mixture was stirred for 1 h. Then, the first mixture is subjected to solid-liquid separation, and the solid obtained from the solid-liquid separation is pretreated high-ash anthracite. After measurement, the ash content in the pretreated high ash anthracite is 7%, the alumina content in the ash is 18.7%, the silicon oxide content in the ash is 29.5%, and the content of oxygen-containing functional groups in the pretreated high as...
