Abstract
Influence of γ-irradiation of lignite from Karaman-Ermenek deposit of Turkey on its following thermal decomposition was studied. The absorbed dose of preliminary irradiation is £> = 5.4-410.4 kGy, the lignite decomposition temperature is t = 350-600°C. H2, CO, C02 and hydrocarbon gases CrC4 are identified as a products during lignite semi coking. It’s shown that the quantity of semi coke gas volume and hydrocarbon gases concentration extremely depend on the preliminary radiation dose, the maximum gas volume corresponds to the absorbed dose 20-70 kGy. This experimental fact is explained by the competition between radiation induces processes of destruction and polycondensation in the lignite organic mass.
