掺杂型mn-la/ti-pilc催化剂的低温scr脱硝研究
, PP. 1372-1376
Keywords: la掺杂,mn/ti-pilc,低温scr
Abstract:
？采用共浸渍法制备了mn/ti-pilc和la掺杂的mn-la/ti-pilc(k为la和mn物质的量比,k=0/1、1/4、1/12和1/20)四种催化剂。研究了la的掺杂对催化剂的低温脱硝效率的影响,同时通过bet、h2-tpr、nh3-tpd和xrd等方法对催化剂进行表征。结果表明,la的掺杂使催化剂的还原温度向低温方向迁移,氧化还原能力得到了提高,催化剂的表面酸量得到提高;la的掺杂有利于催化剂活性的提高,其中,mn-la/ti-pilc(k=1/12)催化剂的低温scr的脱硝活性最高。
