Vinyl benzylchloride (VBC) and divinylbenzene (DVB) were used to prepare a new adsorbent for CO2 capture by the high internal phase emulsion technique. Effects of surfactant, water fraction, monomer ratio, and porogen type on the properties of the adsorbent were studied to select a suitable condition for preparation. Optimal properties were obtained from 90 vol% water fraction, 20 wt% of three component surfactants, 65/35 volume ratio of DVB/VBC and chloroethylbenzene porogen. The new material had a surface area of 150 m2/g with an adsorption capacity of 0.106 mmol/g.
