    复合黏结剂代替部分煤焦油制备脱硫脱硝炭的试验研究

    Experimental study on preparation of desulfurated and denitrated activated charcoal using compound binder as a partial substitute of coal tar

    • 摘要: 以太西无烟煤为主要原料、不粘煤和1/3焦煤为辅料制备煤粉,采用复合黏结剂代替部分煤焦油制备脱硫脱硝炭,研究了不同配煤比例对制备的脱硫脱硝炭的耐压强度、吸附性能、孔径分布的影响。结果表明:增加太西无烟煤的比例有利于微孔的发育,增加1/3焦煤和府谷煤的比例有利于中孔的发育;脱硫脱硝炭的强度随着烧失率的增大而不断下降,用复合黏结剂代替部分煤焦油制备的脱硫脱硝炭样品的耐压强度与吸附性能指标均可达到客户的要求。

       

      Abstract: Experimental study is made on the preparation of desulfurated and denitrated carbon using compound binder in place of part of coal tar, with the anthracite of Shanxi Province as the main material and the non-sticking coal and 1/3 coking coal as auxiliary materials. It is intended to investigate the effect of proportions of blending coal on adsorptivity and pore size distribution of activated carbon on strength of prepared carbon. Result of study indicates that: increasing the blending proportion of Taixi anthracite is helpful to the development of micropores while the increase of the proportions of 1/3 coking coal and Fugu coal is conducive to the formation of medium-sized pores; the strength of prepared carbon tends to gradually weaken with increase of loss on ignition; and use of compound binder as a partial substitute for coal tar makes it possible for the prepared carbon to be up to the user-specified standards in both absorptivity and strength.
