摘要

A K-promoted HTlc was synthesized and tested for its reversible CO2 capacity between 250 and 500 ℃. Non-equilibrium dynamic adsorption and desorption isotherms were measured between 65 and 980 torr using 20 or 50 torr steps and a 45 min duration between steps. The absolute CO2 capacity on K-promoted HTlc increased with decreasing temperature, with CO2 loadings of 2.25 and 1.02 mol/kg respectively at 250 and 500 ℃ and 980 torr. The reversible CO2 working capacity obtained between 65 and 980 torr exhibited a maximum at 450 ℃, with a value of 0.55 mol/kg compared to 0.11 and 0.46 mol/kg at 250 and 500 ℃, respectively. It was surmised that three temperature dependent, highly coupled, completely reversible, equilibrium driven but kinetically limited reactions were taking place, with the first one being a rapid and reversible chemisorption of CO2 that initiated the entire process.
