I, Eyubov Karim Tahir worked in the Institute of Radiation Problems of the Academy Sciences of Azerbaijan, so my research is linked with the fields of nuclear physics and radiation chemistry. My thesis work is devoted on producing of molecular hydrogen from oil and oil-polluted waters by the irradiation of γ-rays. As it is known, producing and using of alternative sources of energy is one of the most actual problems of modern science. And these sources must be ecologically pure. So, molecular hydrogen is most perspective source for the matter in that. Using of high energy sources, such as γ-rays, α-rays, electronic beam and others, for hydrogen producing from different materials is interesting both scientific and practical fields of view. My thesis work was devoted on deciding of two problems: hydrogen producing and purification of oil-polluted waters. The got results confirm of selected way: the radiation-chemical yield of molecular hydrogen is equal to hundreds molecules per 100 eV of used energy. This is a good value in comparison with traditional ways. And also simultaneously, toxicity of polluted water decreases in several times, that useful from ecological aspect. There were received other useful products: methane, ethane, propane, and some spirits. Besides, it was found optimal conditions for maximal transform of radiation energy to final products, i.e. dose of radiation, composition of polluted water, temperature of process and etc. Results were published in scientific journals both in Azerbaijan and abroad.
