Abstract: Methods of converting a variety of fluorinated materials into anhydrous hydrogen fluoride are described. The methods include thermally decomposing the fluorinated materials into a gaseous effluent comprising hydrogen fluoride and carbon dioxide. This gaseous effluent is then treated with carbon at a temperature of at least 830° C., converting the carbon dioxide to carbon monoxide (CO) and producing a gaseous product comprising the hydrogen fluoride, which can be condensed to generate anhydrous hydrogen fluoride. These methods can also be used to convert water contained in the gaseous effluent into hydrogen.

Abstract: The process is described for recycling a heat-treated solid article including a fluorinated polymer having a fluorinated polymer backbone chain and a plurality of groups represented by formula —SO3Z, wherein Z is independently a hydrogen, an alkali-metal cation, or a quaternary ammonium cation. The heat-treated solid article was previously heated at a temperature of at least 100° C. The process includes heating the heat-treated solid article in the presence of water and base to form a fluorinated polymer salt solution, allowing the fluorinated polymer salt solution to cool, and converting the fluorinated polymer salt solution to fluorinated polymer solution wherein Z is hydrogen by cation exchange.

Abstract: The process produces a fluorinated olefin from a fluorinated copolymer having at least one of sulfonic acid groups, carboxylic acid groups, or salts thereof. The process includes heating the fluorinated copolymer at a first temperature not more than 450° C. to decompose at least one of the sulfonic acid groups, carboxylic acid groups, or salts thereof to form a partially pyrolyzed intermediate and subsequently heating the partially pyrolyzed intermediate at a second temperature of at least 550° C. to produce the fluorinated olefin.
