| 英文摘要 | the synthesis of dnl-6 with a high concentration of si(4al) environments [si/(si+al+p)=0.182mol, denoted as m-dnl-6] is demonstrated. this represents the highest reported concentration of such environments in silicoaluminophosphate (sapo) molecular sieves. adsorption studies show that the high si(4al) content in m-dnl-6, with an increased number of bronsted acid sites in the framework, greatly promotes the adsorption of co2. m-dnl-6 exhibits a large co2 uptake capacity of up to 6.18mmolg1 at 273k and 101kpa, and demonstrates high ratios of co2/ch4 and co2/n2 separation. from breakthrough and cycling experiments, m-dnl-6 demonstrates the ability to completely separate co2 from ch4 or n2 with a dynamic capacity of approximately 8.0wt% before breakthrough. importantly, the adsorbed co2 is easily released from the adsorbent through a simple gas purging operation at room temperature to regain 95% of the original adsorption capacity. these results suggest that m-dnl-6 can be used as a potential adsorbent for co2 capture in pressure swing adsorption processes. |
