    摘要： In one aspect, the invention provides a method for the capture of at least one acid gas in a composition, the release of said gas from said composition, and the subsequent regeneration of said composition for re-use, said method comprising performing, in order, the steps of: (a) capturing the at least one acid gas by contacting said at least one gas with a capture composition comprising at least one salt of a carboxylic acid and at least one water-miscible non-aqueous solvent; (b) releasing said at least one acid gas by adding at least one protic solvent or agent to said composition; and (c) regenerating the capture composition by partial or complete removal of said added protic solvent or agent from said composition. Optionally, said capture composition comprising at least one salt of a carboxylic acid and at least one water-miscible non-aqueous solvent additionally comprises water or another protic solvent. In another aspect, the invention envisages a composition which additionally comprises at least one protic solvent or agent and release of the at least one acid gas is achieved solely by subjecting the composition to the application of heat or stripping with a stream of air. The method is typically applied to the capture and subsequent release of carbon dioxide, and offers a convenient and simple process which uses inexpensive consumables and offers significant advantages over the methods of the prior art.

    摘要翻译： 在一个方面，本发明提供了一种用于捕获组合物中的至少一种酸性气体，从所述组合物中释放所述气体以及随后再生所述组合物以供再利用的方法，所述方法包括按顺序进行 步骤：（a）通过使所述至少一种气体与包含至少一种羧酸盐和至少一种水混溶性非水溶剂的捕获组合物接触来捕获所述至少一种酸性气体; （b）通过向所述组合物中加入至少一种质子溶剂或试剂来释放所述至少一种酸性气体; 和（c）通过从所述组合物中部分或完全除去所述添加的质子性溶剂或试剂来再生捕获组合物。 任选地，包含至少一种羧酸盐和至少一种与水可混溶的非水溶剂的所述捕获组合物另外包含水或另一种质子溶剂。 在另一方面，本发明设想了另外包含至少一种质子溶剂或试剂的组合物，并且仅通过使组合物施加热或用空气流汽提来实现至少一种酸性气体的释放。 该方法通常用于二氧化碳的捕获和随后释放，并且提供了使用廉价的消耗品的方便和简单的方法，并且与现有技术的方法相比具有显着的优点。
