ABSTRACT:
A process is provided for the manufacture of a carbonaceous char capable of catalyzing the rapid decomposition of hydrogen peroxide in aqueous solutions. This carbonaceous char is produced from a bituminous coal or a bituminous material that has been carbonized and extensively oxidized at low temperatures (less than 700.degree. C.). The resultant carbonized and oxidized bituminous coal or bituminous material is then contacted with a nitrogen-containing compound in combination with an aliphatic organic compound containing both ether and alcohol functionalities as the temperature of the low-temperature char is increased to minimally 700.degree. C. This treatment results in a high-temperature char which may then be activated as desired. These activated chars show the aforementioned ability to rapidly decompose aqueous solutions of hydrogen peroxide and are also useful for the catalytic chemical conversion of H.sub.2 S, SO.sub.x, NO.sub.x, chloramines, and/or peroxides in liquid and/or gaseous streams.
