Abstract

This work investigates the application of novel sorption materials to heat-powered desalination systems. Two ionic liquids 1-ethyl-3-methylimidazolium acetate (Emim-Ac) and 1-ethyl-3-methylimidazolium methanesulfonate (Emim-Oms) ionic liquids were impregnated in two silica supports, namely Syloid AL-1FP and Syloid 72FP. Emim-Ac and Emim-Oms composite sorbents have been compared on morphology, water vapor sorption equilibrium and heat of sorption. Fourier-transform infrared spectroscopy shows the ionic liquid partly organises on the silica surface. When used in a sorption desalination process powered by low grade heat at 60°C, these composites have exceptionally high theoretical working capacities ranging from 1 to 1.7 gwater gsorbent–1. Experimental tests on a lab scale desalinator show that Emim-Ac/Syloid 72FP in real operating conditions can produce 25 kgwater kgsorbent–1 day–1. To date, this yield is 2.5 times higher than the best achieved with silica gel.
