稻壳经炭化、添加NaOH和NaAlO2水热合成A型沸石-活性炭复合材料，加入凹凸棒石黏土（凹土）成型后采用浸渍法制备CuO-沸石-活性炭-凹土复合烟气脱硝催化剂（CuO-ZCP）。采用XRD、SEM、N2吸附-脱附和NH3-TPD对材料进行了表征，考察了载体类型、反应温度、CuO含量对催化剂脱硝性能的影响。结果显示，沸石-活性炭的引入提高了复合载体的孔隙以及对NH3和NO的吸附，CuO-ZCP脱硝率高于凹土以及商品活性炭和凹土混合制备的脱硝催化剂的活性。催化剂脱硝率随CuO含量的增加而增加。反应温度越高，催化剂脱硝率越高，但温度过高（280℃）会导致活性炭氧化，最佳温度为250℃。

Zeolite A-activated carbon composite (ZC) was prepared from carbonized rice husk by hydrothermal treatment after adding NaOH and NaAlO2. CuO-zeolite-carbon-palygorskite composite denitration catalyst (CuO-ZCP) was then synthesized after mixing zeolite-carbon, palygorskite and copper nitrate followed by calcination in nitrogen. The samples were characterized by XRD, SEM, N2 adsorption-desorption and NH3-TPD. The effects of the type of support, reaction temperature, and CuO content on the catalytic properties of denitration catalyst were also investigated. The results indicated that ZC could increase the porosity of the composite support and adsorption capacities of CuO-ZCP for NH3 and NO. The NO conversion of CuO-ZCP was higher than that of CuO-palygorskite denitration catalyst and CuO-palygorskite-activated carbon composite denitration catalyst. The catalytic properties of CuO-ZCP increased with the CuO content and reaction temperature. Activated carbon in the catalyst could be oxidized at high reaction temperature (280℃). A proper reaction temperature was 250℃.
