摘　　要：以硅溶胶、氢氧化铝为原料,N,N,N-三甲基-1-金钢烷基氢氧化铵为模板剂,采用水热法合成出较高结晶度的SSZ-13分子筛。采用低廉的铜胺配合物为辅助模板剂合成出较高结晶度的Cu-SSZ-13分子筛。采用离子交换法和浸渍法对SSZ-13分子筛制备出Cu/SSZ-13催化剂。相比Cu/ZSM-5催化剂,Cu/SSZ-13催化剂具有更优异的脱硝活性和更宽的活性窗口。用SSZ-13和Cu-SSZ-13分子筛制备的催化剂样品(29)90%NO_x转化率的高活性温度窗口分别为220~480℃、280~460℃。SSZ-13 molecular sieves with high crystallinity were synthesized with silica solution and aluminum hydroxide as raw materials and N,N,N-trimethyl-1-adamantammonium hydroxide as template by hydrothermal crystallization method. Cu-SSZ-13 molecular sieves with high crystallinity were synthesized by using low-cost copper amine complex as auxiliary template. Cu/SSZ-13 catalysts were prepared by ion-exchange method and impregnation method with SSZ-13 and one-pot synthesized Cu-SSZ-13 molecular sieves. Compared with Cu/ZSM-5 catalysts, Cu/SSZ-13 catalysts showed more outstanding NOx reduction rate and wider active temperature window. The NOxconversion of catalyst samples was more than 90% with temperature range of 220 ℃ to 480 ℃ and 280 ℃ to 460 ℃, respectively.
