Mn-Ce/TiO2低温脱硝催化剂的性能OA北大核心CSCDCSTPCD
Study on the denitration characteristics of Mn-Ce/TiO2 catalyst at low temperature
采用等体积浸渍法制备催化剂,在TiO2颗粒表面滴入硝酸锰和硝酸铈溶液,制备需要的Mn-Ce/TiO2催化剂。采用固定床催化剂反应器,以氨气为还原剂,考察了不同锰前体制备的催化剂选择性催化还原NO的活性,研究了负载顺序、温度、负载量、空间速度、O2含量、NH3/NO不同情况下NO的去除率。研究结果表明,温度在160℃、Mn∶Ce摩尔比为8∶1,负载量为18%时,催化剂对NO的去除率可达到90%。
The Mn-Ce/TiO2 catalyst was prepared by the incipient impregnation of instilling nitric acid manganese and nitric acid cerium solution on the surface of the TiO2 particles.Using a fixed bed catalyst reactor and ammonia gas as the reductant,the activation of selective catalytic reduction NO was studied by catalyst prepared in different manganese precursors.And the NO removal rate was also studied under different load sequences,temperatures,load capacities,spa…查看全部>>
