Rapid and intensified screening of a carbon capture adsorbent using a 3D-printed swirling fluidised bed

•CO2 uptake, temperature, & breakthrough times were measured for BPEI sorbent.•Desirable swirling flow regime identified as a function of gas flowrate and bed loading.•CO2 capacity was a function of the flow regimes.•Temperature measurements confirm good thermal control within the TORBED.•The TORBED enables high throughput screening of CO2 adsorbents.
