Supported ionic liquid water sorbent for high throughput desalination and drying

Abstract

The composite material 1-ethyl-3-methylimidazolium methanesulfonate ionic liquid in Syloid AL-1FP silica shows unprecedented water vapor sorption equilibrium properties. Equilibrium data were recorded at different loads of ionic liquid in the silica support (from 1.8%w to 60%w). At loadings >1.8%w, all the composites show type 3 isotherm, therefore conserving the vapor-liquid equilibrium of the bulk ionic liquid/water binary system but with increased dependence between temperature and water adsorbed. This feature makes this composite material particularly suitable for thermally-driven technologies. The composite 60%w 1-ethyl-3methylimidazolium methanesulfonate ionic liquid in 40%w Syloid AL-1FP silica shifts the performance of sorption desalination and drying processes at the unprecedented working capacity of 0.46 gwater/gsorbent (desalination) and 0.82 gwater/gsorbent (drying).

Cycle and performance analysis of a small-scale adsorption heat transformer for desalination and cooling applications

“…The two evaporator system leads to a performance improvement, but also to a more complex process, which is why more work needs to be done to improve the adsorption material as well as the process, i.e. heat and mass transfer [49,50].…”

Design and experimental study of a small scale adsorption desalinator

“…Thus, the adsorption material required per household is 400 kgw d 8 kgw kgsgd = 50 kg sg . Advances in novel adsorbents [41] could reduce this number to 20 kg of adsorption material per household. An adsorption desalinator with 1 ton of material can already supply 20 households today or 50 in the future.…”

Highly modulated supported triazolium-based ionic liquids: direct control of the electronic environment on Cu nanoparticles

“…11 Despite this exciting research using imidazolium-based SILPs, there is no or very little research using different IL-based SILPs, and a fresh approach can unlock a new generation of SILPs for catalytic applications. [12][13][14] In this regard, the highly modulated and greener synthesis of a SILP based-triazolium family appears as an exciting novel alternative. In the case of triazoles, the incorporation of different functional groups into the triazolium ring can be easily obtained using copper-catalysed azide-alkyne cycloaddition (CuAAC), which has emerged as a central transformation of click chemistry (Fig.…”
