摘要：Co2 absorption kinetics in united-developed desulfur solvent (UDS; a multicomponent solvent) and methyldiethanolamine solutions are measured in a disk column under the temperature range from 303 to 323 K and solution concentrations range from 0.35 to 4.371 mol·L-1. Under the condition of UDS concentration of 50% (4.371 mol·L-1) and temperature of 313 K, N and kobs are 5.561 × 10-6 kmol·m-2 ·sec-1 and 4,183.372 sec -1, respectively. The absorption activation energy of Co2 into UDS is 44.92 kJ·mol 1. ? 2012 Copyright Taylor and Francis Group, LLC.
