以不锈钢纤维和商用铜铬银浸渍炭催化剂为主要原材料，采用“湿法造纸 － 高温 烧结”工艺制备了微纤包覆铜铬银浸渍炭复合材料． 利用扫描电子显微镜( SEM) 和 N2 吸 附法考察微纤复合材料的结构和浸渍炭的孔径分布与比表面积． 结果表明，浸渍炭颗粒被 较好地包覆在了不锈钢纤维形成的三维网状结构中，浸渍炭的孔结构特性基本不变，比表 面积略有增加． 利用 X 射线衍射仪( XＲD) 、 X 射线光电子能谱仪( XPS) 和化学吸附仪 ( TPＲ) 考察微纤包覆工艺对浸渍炭活性组分的影响，结果表明大部分活性组分被还原． CO 在颗粒浸渍炭固定床、微纤包覆浸渍炭固定床以及二者床层高度比例为1∶ 1 的结构化 固定床上的催化氧化实验表明，微纤包覆过程使得商业铜铬银浸渍炭对 CO 的催化活性 降低，与复合材料表征结果相符． 

The microfibrous entrapped Cu/Cr/Ag impregnated carbon composites ( MFC) were prepared by wet layup papermaking and sintering process with micronsized stainless steel fibers and commercial granular Cu/Cr/Ag impregnated carbons ( GIC) as main raw materials． SEM images showed that the impregnated carbons were entrapped into a well sinterlocked three-dimensional network of stainless steel fibers． Nitrogen adsorption test showed that the pore structure and specific surface area of the impregnated carbons in composites were almost the same as commercial impregnated carbons． The result of XＲD，XPS and TPＲ all indicated that the active components of impregnated carbon were reduced． Catalytic performances for CO were investigated in structured fixed bed reactor filled with GIC and MFC with the height ratio of 1∶ 1，the experimental results showed that the conversion of CO over MFC decreased，which matched with the results of XＲD，XPS and TPＲ．
