Fast and highly efficient SO2 capture by TMG immobilized on hierarchical micro–meso–macroporous AlPO-5/cordierite honeycomb ceramic materials

Abstract

SO₂ capacity of the obtained TMG–AlPO-5/cordierite honeycomb ceramic (CHC) adsorbent was measured to be 1.13 mol per mol TMG. More importantly, compared with literature reported supported ionic liquids, it is featured by a significantly improved adsorption rate (t_0.9 reduced from >30 min to ∼0.1 min) and negligible pressure drop.
