选择性催化还原(SCR)法脱除NO_x的研究进展

The research and progress in selective catalytic reduction of NO_x

本文介绍了用作NOx选择催化还原的碳氢化物、氨气、尿素等几种还原剂和活性炭、分子筛、金属氧化物、堇青石蜂窝陶瓷、复合载体等几类载体催化剂的研究进展情况,并阐述了各自的优缺点,综述了尿素作为还原剂,复合载体的催化剂将是脱除氮氧化物的研究热点。

Tiffs paper introduced latest advances of reducing agent included CxHy, NH3, CO（NH2） 2 and so on, and introduced several kinds of catalysts used active carbon, zeolite, metal oxides, cordierite, multiple carrier as carriers, selective catalytic reduction of NOx. The advantages and disadvantages of catalyst and reducing agent were discussed. The selective catalytic reduction of removing nitrogen oxides using urea as reducing agent and using multiple cartier catalysts will become a popular subject.
