Application of Mechanochemical Activation and γ-Radiation to Increase the Reactivity of Coal from the Shubarkol Deposit in Hydrogenation

Abstract

The results of the mechanochemical activation of coal from the Shubarkol deposit in an impactgrinding mill and under exposure to γ-radiation with an electron beam on a LU-6 electron accelerator are reported. It was established that, upon the hydrogenation of dispersed coal, the yields of both total liquid products and different distillate fractions increased. The maximum yields of liquid products (66.8%) and gasoline (12.8%) and diesel (18.5%) fractions were noted upon the hydrogenation of coal ground for 30 min. It was shown that the irradiation of coal with an electron beam (a dose of 150 kGy) increased its reactivity in the process of hydrogenation and also facilitated the formation of free radicals and changed the compounds of iron that are the constituents of the catalyst based on natural bauxite from the Turgai deposit.
