摘　　要：通过向萃余煤中添加黏结剂加压成型,进行炭化和活化制备得到平板状炭膜支撑体。结果表明:萃余煤热解的残碳量为79.18%;活化后支撑体的比表面积约为活化前的7～8倍,总孔容增大了4倍;孔隙率和渗透率最大分别为38.04%和6 219.90 L/(m.2h.MPa);对Fe(OH)3胶体的截留率为37.44%After adding binder and pressing to moldings,the residue was made into plate-shaped carbon membrane supporter by carbonization and activation.The results show that the pyrolysis residual of residue is 79.18%.The surface area is nearly 7～8 times of that before the activation,and the total volume increases about 4 times.The maximum of the porosity and permeability are 38.04% and 6 219.90 L/（m2·h·MPa）,respectively.Fe（OH）3 colloid is retained at 37.44% by the carbon membrane supporter.
