The chemical absorption of CO2by an aqueous solution of NaOH has been employed to investigate the mass transfer performance in a tubular reactor with four different inserted components. The effects of combinations of the four inserted components on the mass transfer performance were also studied. The volumetric overall mass transfer coefficients (KGaV) for the tubular reactor were evaluated with the liquid flow rate and gas flow rate as operating variables. The experimental results showed that KGaV increased with the increase of the liquid flow rate while the gas flow rate had a negligible effect on KGaV. The inserted components could increase the values of KGaV of the tubular reactor and greatly intensify the mass transfer process. The KGaV values of the tubular reactor with central components, tube wall components and their combinations were higher than those of the tubular reactor with no inserted components by 8%-47%, 15%-46% and 19%-65%, respectively. Comparison of the overall performance of the four inserted components suggests that in terms of KGaV values, insertion of the U-blades in the tubular reactor offered the best mass transfer enhancement while flat blades offered the worst mass transfer enhancement.
