Process for the catalytic oxidation of ferrous iron in liquid media |
| abstract |
A improved process is provided for the catalytic oxidation of ferrous iron in liquid media in the presence of oxygen. The improvement is provided by the use of a carbonaceous char catalytically active for said oxidation which is prepared by the carbonization and oxidation of a bituminous coal or a bituminous material at temperatures below 700° C. followed by exposure of the carbonized, oxidized char to a nitrogen-containing compound and, during or after said exposure, increasing the temperature to at least 700° C. |
