摘要：

The　oxidation　performance　of　NO　on　Fe　modified　Mn-Ce/Al2O3-TiO2　catalysts　with　10%　Mn　and　2%　Ce　mass　fractions　was　studied　experimentally.　These　catalysts　were　prepared　by　impregnation　method　using　Al2O3-TiO2　composite　oxide　as　support　in　which　the　molar　ratio　of　TiO2　and　Al2O3　was　1　:4.　The　experiments　on　oxidation　performance　of　the　catalysts　were　investigated　in　a　fixed　bed　reactor.　And　the　results　show　that　the　addition　of　Fe　can　significantly　improve　the　oxidation　performance　of　NO　on　the　modified　Mn-Ce/Al2O3-TiO2　catalyst　at　the　condition　of　15　000　h-1　velocity　and　8%　O2　volume　fraction.　As　the　Fe　loading　is　4%,　the　Mn-Ce-Fe　(4)/Al2O3-TiO2　catalyst　presents　the　highest　NO　conversion　and　reaches　86%　at　280　℃.　The　addition　of　Fe　shifts　the　deoxidization　peak　of　Mn-Ce/Al2O3-TiO2　catalyst　to　the　low　temperature　direction　which　could　improve　the　catalytic　activity.　©　2019,　Editorial　Office　of　＂CHEMICAL　ENGINEERING＂　(CHINA).　All　right　reserved.
