Prediction of Cell Voltage and Chlorine Current Efficiency of Aqueous HCI Electrolysis Utilizing an Oxygen Reducing Cathode Based on Artificial Neural Network

摘要

HCI (Hydrogen chloride) is a by-product of many manufacturing processes that use chlorine. For example, chlorine is used to manufacture polyvinylchloride, isocyanates, and chlorinated/fluorinated hydrocarbons, with hydrogen chloride as a by-product of these processes. In the majority of applications, chlorine is used due to its high reactivity for production of chlorine containing intermediates, e.g. phosgene or chlorinated aliphatic or aromatic compounds. Hydrogen chloride can be a direct by-product of chlorination, e.g. of substitution reactions, but mostly it is generated in subsequent production steps while removing chlorine atoms in order to attain chlorine-free final products.
