Abstract
The pH of modified liquid TEPA (T1AN, T2AN, and T3AN) was slightly reduced; however, both viscosity and thermal stability were increased. The increased viscosity of the modified amines was indicative of an increase in attraction between the amine molecules; accordingly, amine leaching decreased noticeably and thermal stability of amines increased. Modified amine-impregnated sorbent (ST1AN and ST2AN) showed slight decrease in CO2 adsorption capacity but noticeable increase in rates of adsorption, durability during cyclic tests, and desorption characteristics compared to TEPA-impregnated sorbent (STEPA).
