Abstract

A process for the destruction of organic compounds selected from the group consisting of nitriles, aromatics, heteroaromatics, amides, organic acids, aldehydes and alcohols from wastewater, comprising contacting volatilized wastewater with a catalyst at an elevated temperature in the absence of added oxygen, so as to convert volatile organic compounds and ammonia to a mixture comprising hydrogen and carbon dioxide which are separated and removed from the stream, yielding a purified aqueous stream, substantially free of organic compounds.
