Regularities in gas formation at γ-radiolysis of coals and petroleum residues

The regularities of H2, CO, and CH4 formation at γ-radiolysis of brown coals, hard coal, petroleum-bituminous rock, petroleum bitumen, tar, and petroleum residue have been studied at room temperature, absorbed radiation dose 30–2400 kGy, dose intensity 1.6–21.1 kGy/h. The radiation-chemical yields of these gases were found to constitute °Gr≅0.005–0.07 mol/100 eV for coals, and °Gr≅0.3–0.6 mol/100 eV for petroleum residues.
