Process for production of carbonaceous chars having catalytic activity

Abstract

A process is provided for the production of a catalytically-active carbonaceous char. By this process, a nitrogen-containing compound is combined with an uncarbonized nitrogen-poor carbon-containing material. The resulting mixture is then carbonized and oxidized at temperatures less than 600° C. The resulting low-temperature char is next heated to temperatures greater than 600° C. and subsequently activated with H2O, CO2, or O2, singly or in any combination, to result in the catalytically-active carbonaceous char. The resulting catalytically-active carbonaceous char has utility for the chemical conversion of peroxides, hydrides, SOx, NOx, and chloramines in liquid and/or gaseous media.
