| 摘 要： | 引言目前人们普遍认为大气中二氧化碳(CO2)浓度的提高导致了温室效应,全球变暖;气候异常,灾难性气候增加。据文献报道[1],人类活动可能产生的3.67万亿吨CO2,现已排放近半。CO2是种宝贵的碳资源,若加以充分回收利用,既能减轻环境污染,同时也能带来经济效益。

| Abstract: | 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),Mn/HZSM-5(25). |
