Abstract:
As a kind of environmentally friendly solvent, ionic liquid has special advantages of absorbing SO2. The technology of ionic liquids desulphurization has shown a progress from fundamental researches to industrial applications. The research on desulphurization and absorbing properties of guanidinebased, imidazoliumbased and alcohol aminebased ionic liquids, by means of experimental and quantum chemistry calculative methods and the applications including ionic liquid circulatory desulphurization technology, ionic liquid polymerization, ionic liquid supporting particles and supporting membrane contactor were summarized in detail. Meanwhile,the progress of the ionic liquid desulfurization technology was analyzed and predicted.
