Development of New Potassium Carbonate Sorbent for CO2 Capture under Real Flue Gas Conditions

In this paper, the development of a new potassium carbonateon alumina support sorbent prepared by impregnating K2CO3 with an industrial grade of Al2O3 support was investigated. The CO2 capture capacity was measured using real flue gas with 8% CO2 and 12% H2O in a fixed-bed reactor at a temperature of 65 °C using breakthrough curves. The developed sorbent showed an adsorption capacity of 66.2 mg...

A computational investigation on the structural features of alkanolamine solvents for CO2 capture process from power plant flue gas

Investigation of carbon dioxide capture from hydrogen using the thermal pressure swing adsorption process: Central composite design modeling

In this study pre-combustion capture of carbon dioxide from hydrogen was performed using a 5A zeolite adsorber. A one column thermal pressure swing adsorption (TPSA) process was studied in the bulk separation of a CO2/H2 mixture (50:50 vol%). The adsorption dynamics of the zeolite bed were investigated by breakthrough experiments to select the suitable range for operational factors in the desig...

Adsorption Performance Indicator for Power Plant CO2 Capture on Graphene Oxide/TiO2 Nanocomposite

This study presents the adsorption performance indicator for the evaluation of thermal power plant CO2 capture on mesoporous graphene oxide/TiO2 nanocomposite. To begin, this adsorbent was synthesized and characterized using N2 adsorption-desorption measurements (BET and BJH methods), X-Ray Diffraction (XRD), Field Emission Scanning Electron Microsc...

Design of a H2 Pressure Swing Adsorption process at an advanced IGCC plant for cogenerating hydrogen and power with CO2 capture

A novel hydrogen pressure swing adsorptionsystem has been studied that is applied to an advanced inte-grated gasification combined cycle plant for cogeneratingpower and ultrapure hydrogen (99.99? mol%) with CO2capture. In designing the H2 PSA, it is essential to increase therecovery of ultrapure hydrogen product to its maximum sincethe power consumption for compressing t...
