摘要：

A novel honeycomb micro packed bed (HMPB) was fabricated by wall-flow honeycomb ceramics in order to resolve the issues of high pressure drop and low catalysts utilization efficiency in common packed adsorption bed. The flow condition and pressure drop of HMPB were investigated and the application in pressure swing adsorption (PSA) process of carbon dioxide capture were considered based on both experiments and mathematical simulation. Results showed that the pressure drop of HMPB was so low, uniform distribution of flow was realized and absorption duty was averaged. Experiments on CO2-N2 adsorption and dynamic adsoption capacity of activated carbon were conducted by usage of HMPB. Then influence of pressure, concentration and flowrate on breakthrough curves were considered to reveal the rules of adsorbent recovery and the effects of continuous absorption process on bed pressure. The experimental data agreed well with the model of micro packed bed. HMPB is an appropriate structure of packed adsorption bed and of great potential in industrial application. © 2017, Zhejiang University Press. All right reserved.
