Performance analysis of temperature swing adsorption for CO2 capture using thermodynamic properties of adsorbed phase

摘要: Abstract The present work describes the theoretical research frameworks mainly for thermodynamic properties of adsorbed phase, which is applied in field temperature swing adsorption (TSA) CO 2 capture. heat and specific capacity phase are quantitatively analyzed based on isotherm data activated carbon at ranging from 273 K to 358 K. Employing such , effect four cyclic parameters energy-efficiency performance 4-step TSA processes evaluated pump theory including minimum separation second-law efficiency. results show that regeneration has been increased with considering amount sensible accounts approximately one-sixth one-fourth total thermal energy consumption. However, corresponding efficiencies just drop 1.43–7.21%. Although consumption higher than traditional absorption technologies, slightly due lower heating requirements auxiliary power.
