The first mode is implemented partial oxidation carbonized residue in coal vodokislorodnogo fluid stream at a temperature of 923 K and a pressure ~30 MPa. Detected flow coupled processes of oxidation and carbon balance formation of inflammable gases (hydrogen content in the products increase by 26 % its relative amount in the original sample) due to the participation of the molecules H2O in redox reactions.
