Meeting Target Emissions in Low Temperature Operations

With increasingly stringent emission requirements put in place by authorities and communities, the industry is constantly forced to reevaluate its emission strategy. 

Until today, there has been no cost-effective way to successfully ensure an SCR catalyst meets NOx emissions reduction targets when the flue gas is at lower temperatures. But now, a catalyst with an optimal temperature range of operation between 150°C/300°F – 200°C/392°F is a reality. This type of catalyst is ideal for tail-end SCRs after bag filters, scrubbers, or heat exchangers while still meeting more stringent emissions requirements.

Umicore’s R&D team has developed the TripleCat DNX-LT SCR catalyst, with a proven 3-fold activity increase in the 150-170°C range as compared to a traditional SCR catalyst.
