| Abstract: | Latest studies on adsorption separation via π-complexation were reviewed.Basic theory of π-complexation was briefly introduced.Molecular orbital theory and natural bond orbital theory calculation were summarized to analyze investigation situation of complexation mechanism.Common preparation technologies of solid π-complexation adsorbents were given.Deactivation behaviors of π-complexation adsorbents were studied.Applications of π-complexation adsorbents for several difficult separation processes,namely CO recovery,olefin-paraffin separation,aromatics-aliphatics separation,desulfurization of transportation fuels and removal of dienes from olefins were introduced and discussed in detail.Some suggestions on developing applications of π-complexation in industry were put forward. |
