Development of Polymer from High Internal Phase Emulsion for CO2 Adsorption

Polyvinylbenzyl chloride-divinylbenzene was prepared using the high internal phase emulsion (HIPE) technique and modified with ethylenediamine and triethylenetetramine. All adsorbents were characterized witha fourier transform infrared spectrometer, elemental analyzer, and surface area analyzer. These adsorbents were to be used as adsorbents for a CO2 adsorption study. The experiments were carried out at room temperature and atmospheric pressure using dry 4% CO2/N2 feed gas. The adsorption capacity results showed that the triethylenetetramine adsorbent (0.3283 mmolCO2/g-adsorbent) had a greater adsorption capacity than the ethylenediamine adsorbent (0.3172 mmol CO2/g- adsorbent).
