Benzylamine (BZA) has been identified as a promising candidate for CO2 capture process; however the evalu-ation of BZA in the packed column was very few. Thus, in this work, the absorption and regeneration performance of un-blended BZA solvent as well as a series of amine concentrations and ratios in the formulations were studied using a semi-batch bubbling reactor. And due to the formation of ivory-white precipitates in solvents containing higher BZA ratios, a 4:1 molar ratio of MEA/BZA mixed solvent was used to study its performance in a pilot-scale test bed. The results showed that a higher BZA ratio in the MEA/BZA mixed solvent resulted in a faster absorption rate, a higher mass transfer and heat transfer rate and a better cyclic performance, but the mass transfer rate of BZA decreased more quickly than MEA with the increase of CO2 loading of the solvents. In addition, at high CO2 loading in the MEA/ BZA mixed solvent with a molar ratio of 4:1, the ivory-white precipitates were generated which could cause blockage of the packing in the absorber, the stripper and the liquid pipelines.
