Alkali resistant deNOx catalysts
However, PILC’s with other metals as active components did exhibit rather high activities, and good resistance towards K-contamination. Since these catalytic systems still are yet to be optimized, we have promising candidates as alternative catalysts for alkali resistant SCR catalysis. This indcludes also other metals on other supports which seem interesting, since it is expected that the active sites are less dependent on the sensitive Lewis/Brøndsted acid pair of the V205 based systems. These alternative supports have provided insight to an interesting alternative strategy for obtaining alkali resistant SCR catalysts. It is possible to keep the alkali compounds away from the active sites, by having carrier materials with superior K-affinity. These systems seem to have rather high catalytic activities — atso after potassium impregnation. The most valuable results of the project form the base of the proceeding PSO-project FU5201 'DeNOx catalysis in biomass fired plants'
