Effects　of　adsorbent　type,　operating　conditions　of　discharge,　and　cyclic　operation　on　the　removal　of　NOx　in　adsorption-discharge　plasma　decomposition　process　were　investigated.　Among　the　four　kinds　of　zeolites　(ZSM-5,　MOR,　SAPO-34　and　SSZ-13)　investigated,　SSZ-13　showed　the　highest　NOx　adsorption　capacity　and　lowest　adsorption　strength,　which　were　beneficial　to　prolong　the　adsorption　period　and　promote　the　desorption　and　decomposition　of　NOxby　plasma.　The　results　of　temperature-programmed　desorption　and　infrared　spectroscopy　showed　that　NOx　was　mainly　physically　or　weakly　chemically　adsorbed　on　the　surface　of　SSZ-13,　while　a　small　amount　of　NOx　was　converted　into　strongly　adsorbed　species　such　as　NO3-　and　NO2-.The　removal　of　NOx　adsorbed　on　SSZ-13　by　plasma　is　significantly　affected　by　the　operating　conditions　of　discharge.　Compared　with　N2-purge　discharge　and　sealed-discharge,　higher　NOx　removal　efficiency　and　energy　efficiency,　less　residual　NOx　on　the　adsorbent,　and　lower　N2O　selectivity　can　be　obtained　simultaneously　by　using　sealed-discharge　first　and　thenN2-purge　discharge.　The　removal　performance　of　NOx　can　be　maintained　during　cyclic　operation　of　the　adsorption-plasma　decomposition　process,　without　significant　changes　to　the　crystal　and　pore　structures　of　SSZ-13　after　six　cycles.　©　2022,　Editorial　Board　of　China　Environmental　Science.　All　right　reserved.
