Abstract:
The present disclosure provides methods for pre-treating activated carbon before it is used in a dehydrochlorination process. The methods can comprise mixing the activated carbon with an acid, an oxidizing agent in a liquid phase, or an oxidizing agent in a gas phase. Activated carbons undergoing one or more of these methods can exhibit improved stability during the dehydrochlorination process.
