Carbon Dioxide Absorption using Solid Sorbents Incorporating Purified Components of Tetraethylenepentamine

Abstract Tetraethylenepentamine (TEPA) components are separated by fractional distillation, and the structure of each fraction is established using spectroscopic methods. Then, solid sorbents incorporating these components are prepared, and the capacities and rates of CO 2 absorption of the sorbents are evaluated to elucidate how the molecular structure affects the absorption performance.
