Chemical absorption of carbon dioxide with NaOH in non-Newtonian w/o emulsion

摘要

Carbon dioxide was absorbed into water-in-oil (w/o) emulsion composed of aqueous NaOH droplets as a dispersed phase and benzene solutions of polybutene (PB) and polyisobutlene (PIB) as a continuous phase in a flat-stirred vessel to investigate the effect of non-Newtonian rheological behavior on the rate of chemical absorption of CO_2, where the reaction between CO_2 and NaOH in the aqueous phase was assumed to be a pseudo-first-order reaction. It was expressed that PIB with elastic property made the rate of chemical absorption of CO_2 accelerated by comparison of k_L in the non-Newtonian liquid with that in the Newtonian liquid.
