Oxidation adsorption of NO was investigated on HZSM-5 without and with transition-metal-salt [3.85%(mass) of metal] as adsorbents in a fixed bed.These adsorbents were characterized by SEM
BET
XRD and XRF.The results demonstrated that both HZSM-5 and transition-metal-salt-modified HZSM-5 can efficiently remove NO from CO2
reducing to a level of less than 0.1?10-6
but for HZSM-5 exist of CO2 will significantly affect NO adsorption.Co/HZSM-5(25)is the best adsorbent with the highest NO adsorption capacity
while the results of NOx-TPD revealed that there is good feasibility of industrial application for Cu/HZSM-5(25)
