Abstract

In the field of CO

capture from flue gas

the synergistic improvement of CO

capture efficiency of amine solutions and low-temperature efficient regeneration is a key issue that urgently needs to be solved in industrial applications. Ce@C (Ce concentration of 0.2 mol/L)

Mn@C (Mn concentration of 0.2 mol/L) and

Mn@C (

(Ce):

(Mn)) were prepared by hydrothermal method. Compound alcoholamine absorbents were constructed by monoethanolamine (MEA) and N-methyldiethanolamine (MDEA) as the amine component (total mass of 40 g). The surface morphologies

microstructures and electronic states of the catalysts were characterized by SEM

TEM and XPS

and the CO

absorption-desorption performances for the compound alcoholamine absorbents with the catalysts were studied. The results show that the compound alcoholamine absorbent (1E2D) composed of MEA and MDEA with mass fractions of 10% and 20%

respectively

has relatively high CO

absorption-desorption performance

with the CO

absorption loading amount of 8.648 × 10

-2

g/g (absorption temperature of 313.15 K

same below)

the CO

desorption amount of 5.867 × 10

-2

g/g (desorption temperature of 363.15 K

same below) and the desorption efficiency of 67.844%. Compared with 1E2D

after adding 1Ce1Mn@C with mass fraction of 0.05% to 1E2D

the CO

absorption loading amount can be increased by 12.26%

the CO

desorption amount can be increased by 30.74% and the desorption energy consumption can be reduced by 14.6%. After five continuous cycles

the system exhibits good stability.
