Removal and destruction of halogenated organic and hydrocarbon compounds with porous carbonaceous materials

摘要

A process for the removal and destruction of organic compounds in liquid and gaseous streams by complete oxidation of the organic compounds in the presence of a carbonaceous catalyst at temperatures below about 400° C. is disclosed. The process involves removal of organic compounds in a regeneration step from adsorbents containing organic compounds adsorbed thereon, in which the organic compounds have been previously removed from contaminated fluid streams in an adsorption step, and destruction of the contaminants in an oxidative destruction step by contacting the organic compounds with a carbonaceous catalyst in the presence of oxygen. The process involving oxidation catalysts optionally doped with transition metal oxides is particularly useful for the complete destruction of volatile organic chemicals found in contaminated groundwaters.
