The potential for increasing the use of catalytic carbons in commercial applications

A carbon catalyst, prepared either by oxidizing activated carbon with air at 500-700??C or by oxidizing activated carbon with boiling nitric acid followed by heating it to 500-700??C, is the subject of this paper. This catalyst, designated OAC500-700, catalyzes the removal of hydrogen chloride from alkyl halides. Because OAC500-700 retains adsorptive properties of an activated carbon it can be used both to adsorb pollutants from liquid or gaseous streams and to convert them to recyclable products. A highly-developed micropore structure is not required for all uses of activated carbon or a catalyst produced from it. A comparatively inexpensive (\$325/ton projected) low surface area (
