Publication number: 20110274607Abstract: The catalytic behaviour of vanadia-supported zeolite catalysts with different SiO2/Al2O3 ratios was tested for the SCR of NO with ammonia. The SCR activity was found to be directly correlated to the total acidity of the catalysts. On the surface of these zeolites the V2O5 was highly dispersed and amorphous in nature. After the impregnation with vanadium and subsequent poisoning with potassium oxide not much change in micro-pore structure of HZSM5 was observed by N2 adsorption studies. Interestingly, potassium-doped HZSM5 and HMORDENITE catalysts showed high resistance to deactivation because of the unique nature of the material exhibiting higher surface area and acidity than the conventional V2O5—WOx/ZrO2 or TiO2 catalysts. Consequently, a possible application of these alkali-tolerant SCR catalysts in biomass fired power plants can be envisaged.Type: ApplicationFiled: April 1, 2011Publication date: November 10, 2011Applicant: TECHNICAL UNIVERSITY OF DENMARKInventors: Putluru Siva Sankar Reddy, Anders Riisager, Rasmus Fehrmann
