超低温度下催化脱销工艺分析

Analysis of catalytic outlet process at ultra low temperature

针对目前选择性催化还原脱硝技术在使用过程中需要对废气进行高温加热、成本高、在应用过程中催化剂极易出现中毒失活、可靠性差的问题,提出了一种新的超低温催化脱硝技术,以碳基材料催化剂为核心,实现了在"超低温度"下的催化还原。实际应用表明,新的催化技术能够实现在200℃下的高效率脱硝,脱硝率达到了73.8%,对降低脱硝成本、减少环境污染具有十分重要的意义。

In view of the high temperature heating,high cost,toxic deactivation and poor reliability of the waste gas in the process of selective catalytic reduction and denitrification,a new ultra-low temperature catalytic denitrification technology is proposed.The catalytic reduction at"ultra-low temperature"is realized with carbon-based material catalyst as the core.Actual application shows that the new catalytic technology can realize high efficiency denitrification at 200℃,and the denitrification rate reaches 73.8%,which is of great significance to reduce denitrification cost and reduce environmental pollution.
