摘要：

To mitigate climate change and reduce CO2 emissions, a systematic study on the capture of CO2 from dry flue gas by temperature vacuum swing adsorption (TVSA) was conducted. With zeolite 13X as adsorbent, a four-bed TVSA with continuous feeding was designed, and a mathematical model was established for numerical simulation. Results showed that with the productivity of 1.7 mol•(kg ads)-1•h-1 and energy consumption of 3.14 MJ•(kg CO2)-1, CO2 purity of 97.54% and CO2 recovery of 96.79% can be obtained by the four-bed TVSA process. The effect of feed flowrate, recycle time and vacuum level on purity, recovery, productivity and energy consumption was investigated. Additionally, the pressure and temperature behaviors in the column were analyzed, and the distribution of gas phase and adsorbed phase concentration in the axial direction was discussed in detail. The good performance indicated that TVSA will have the potential to be a cost-effective process capable of producing high purity and high recovery CO2 product. © All Right Reserved.
