Effect of concentration on amine-modified kenaf as a sorbent for carbon dioxide adsorption in a pressure swing adsorption system

Amongst the strategies applicable for CO2 capture and sequestration, the adsorption process has a high potential to be applied as an alternative CO2 separation strategy as it offers large adsorption capacity, requires low energy for regeneration with economical equipment cost, prevents corrosion pro...
