Gas formation regularities at the consecutive and simultaneous impact of ionizing radiations and heat on Turkish lignites

The regularities of formation of gases H2, CO and hydrocarbons C1–C4 at the consecutive and simultaneous influence of ionizing radiations and heat on Turkish lignites of Karaman–Ermenek deposit was researched. It is shown that at the consecutive influence of radiation and heat the gas yield depends extremely on the preliminary irradiation dose. The simultaneous influence of these factors on lignite leads to the gas yield increase which is connected with acceleration of the active radiolytic particles’ diffusion and breaking off reactions with their participation. Under the influence of the accelerated electron beam lignite decomposes with the relatively high radiation-chemical yields than under the influence of gamma radiation which is connected with acceleration of the diffusion processes due to the irradiated sample’s heating.
