一种煤基脱硫用活性炭的制备方法
摘要：
本发明公开了一种煤基脱硫用活性炭的制备方法，包括：分别将太西无烟煤，1/3焦精煤以及不粘煤磨成200目通过率在80％以上的煤粉；利用所述太西无烟煤、1/3焦精煤以及不粘煤为原料进行配煤，以得到混合原料煤；分别取所述混合原料煤、粘结剂以及水为原料搅拌混合均匀，以得到煤膏；将所述煤膏挤压成型、固化，然后进行氧化处理、炭化处理和活化处理，以制得活性炭。本发明选用太西无烟煤、1/3焦精煤以及不粘煤，配煤制备活性炭，得到了既拥有很好的强度，又拥有优质的吸附/脱附性能的煤基脱硫用活性炭。
摘要（英）：

The invention discloses a preparation method of coal-based activated carbon for desulfurization. The method comprises steps as follows: Taixi anthracite, 1/3 of cleaned coking coal and non-caking coalare ground into 200-mesh coal powder with the passing rate of 80% or above respectively; the Taixi anthracite, 1/3 of cleaned coking coal and non-caking coal are blended as raw materials, and mixed raw coal is obtained; the mixed raw coal, a binding agent and water are taken as raw materials, stirred and mixed uniformly, and coal paste is obtained; the coal paste is formed by extrusion and cured,oxidation treatment, carbonization treatment and activation treatment are performed, and the activated carbon is prepared. The activated carbon is prepared from the Taixi anthracite, 1/3 of cleaned coking coal and non-caking coal, and the coal-based activated carbon for desulfurization has good strength and excellent adsorption/desorption performance.
