摘要

低温下催化剂活性和抗毒性不足限制了低温选择性催化还原(SCR)脱硝工艺的工业应用。采用超声波浸渍法以活性炭纤维为载体

负载CuO、ZrO_2制备催化剂

通过比表面积测试、X射线衍射分析、扫描电镜等手段对催化剂进行表征

并利用固定床反应器探讨其低温SCR脱硝性能

考察了经浓硝酸处理后的活性炭纤维、CuO与ZrO_2单独作为活性组分、CuO与ZrO_2同时作为活性组分对脱硝活性的影响。结果表明:相对于系列CuO/ACFN、系列ZrO_2/ACFN催化剂

系列CuO-ZrO_2/ACFN催化剂的低温脱硝性能有较大的优势

3:1CuO-ZrO_2/ACFN催化剂在260℃时脱硝效率最大值为92%。

Abstract

On the basis of a fixed-bed reactor

the influence of copper and zirconium that supported by activated carbon fiber(ACF) on the denitration activity was studied. The denitrition efficiency with the nitric acid disposed ACF

CuO and ZrO_2 as the active components alone

and the CuO with ZrO_2 as the active components simultaneously

was investigated. The results show that

compared with the CuO/ACFN catalysts and the ZrO_2/ACFN catalysts

the low temperature denitration performance of the CuO-ZrO_2/ACFN catalysts has greater advantage. Besides

the denitration efficiency of the 3:1 CuO-ZrO_2/ACFN catalyst reached the maximum 92% at 260 ℃.
