- *Abstract
-
Chlorine generation is one of the most important processes for a chemical industry, as chlorine is a key component for production of many polymers, notably polyvinyl chloride, polyurethanes, and polycarbonates. The existing chlorine generation techniques involve the use of expensive and precious noble metals such as platinum and rhodium. This invention discloses a novel technique comprising the use of non-noble metal based oxygen depolarized cathodes (ODCs) for HCL recovery and chlorine generation.
