Hypercrosslinked natural biopolymers with quasi-unimodal micropores for carbon capture
Carbon Capture Science & TechnologyUltra-microporous solid sorbents with high CO2 adsorption capacities and gas selectivity are preferred for carbon capture. Here we deliver such sorbents via a combination of narrow micropores, lack of mesopores and an abundance of CO2-philic functional ...

Ammonia Offgassing from SA9T [PDF]
, 2011 NH3 is a degradation product of SA9T, a solid-amine sorbent developed by Hamilton Sundstrand, that is continually emitted into the gas stream being conditioned by this sorbent. NH3 offgassing rates were measured using FTIR spectroscopy using a packed bed

The Canadian Journal of Chemical Engineering, EarlyView.Comparison of PSA and amine‐based absorption for syngas purification shows that PSA offers lower energy intensity, global warming potential, and minimum selling price, making it a more sustainable option. However, absorption achieves higher syngas purity. A GREENSCOPE‐based multi‐criteria assessment guides optimal process selection.
