The　present　work　contains　the　studies　of　catalytic　reduction　of　NO　with　CO　over　20　wt.%　bimetallic　Fe-Cu　transition　metal　oxides　supported　on　rice　hull　ash　(RHA)　and　γ-Al2O3,　which　were　prepared　by　various　procedures.　All　catalysts　contained　CuO　and　Fe2O3　alongside　with　CuFe2O4.　The　catalytic　activity　kinetics　for　NO　and　CO　reduction　reaction　mechanism　was　obviously　improved　over　the　synthesized　RHA　when　compared　to　alumina　support.　And　bimetallic　metal　catalyst　Fe2Cu1/RHA　demonstrated　a　high　conversion　of　NO　at　all　the　temperatures　examined.　This　was　due　to　the　strong　interaction　of　Cu-Fe　with　the　amorphous　silica　and　activated　carbon　in　RHA　and　high　dispersion　on　the　supporter.　NO　was　almost　reacted　to　N2　over　Fe2Cu1/RHA　from　room　temperature　to　500　and　O2　has　little　influence　on　it　in　our　experiment　conditions.　About　100%　CO　was　oxidized　after　150　over　Fe2Cu1/RHA.　All　the　materials　showed　an　unchanged　stability　over　the　period　of　20h.　Metallic　copper　and　iron　were　the　active　species.　The　present　results　suggest　that　bimetallic　Fe-Cu　transition　metal　oxides　supported　on　rice　hull　ash　(RHA)　can　be　used　as　an　applicable　catalyst　to　selectively　reduce　NO　and　CO.　©　ICOPE　2019　-　7th　International　Conference　on　Power　Engineering,　Proceedings.　All　rights　reserved.
