摘要
Abstract
The research and development of high efficiency catalysts were the core to low-temperature NH3 selective catalytic reduction (NH3-SCR) denitration technology.The low-temperature NH3-SCR catalysts were introduced in detail from two aspects of active components (single oxides and complex oxides) and carriers (metal oxides,carbon materials and molecular sieve).The research status of the catalysts was summarized,and their resistance performances to H2O and SO2 and their deactivation mechanisms were discussed.It was pointed out that the focus of future research was to improve the resistance performances to H2O and SO2 of the low-temperature NH3-SCR catalysts as well as to keep high activity.关键词
