The main factors restricking the application of Selective Catalytic Reduction (SCR) technology in China to control NOx emission are the problems of catalyst cost for SCR denitrification and the potential secondary pollution of heavy metalls.For this reason
the research achivements for catalysts of SCR denitrifucation by NH3 and hydrocarbon have been expounded respectively
such as metal oxides
metal ion exchanged zeolites
titanium pillared clay
Al2O3 supported heavy metalls
and rare earth oxides catalysts
and including principles of selecting a suitable catalyst
reation mechanism
catalytic activity
temperature range of activity
and effects of H2O and SO2 in the flue gas etc.
and direction for further improving catalytic activities being proposed.
