Abstract
The reaction of thermal and electron-excited sulphur atoms have been investigated at
the radiolvsis of C02 -H2S - S8 mixtures. It was shown that thermal sulphur atoms were formed
at the H2S radiolysis transform SH-radical to H2 at the thermoradiolysis of C02-H2S
mixtures.Activation energy of process was equal 19.3±1.8 kj/mol. Electron excited sulphur
atoms were created at the octasulphur radiolysis, participated in the tear-reaction at T = 300-320
K. Total yield of synthes-gas and sulphur was equal 13-14 mol/100eV.
The present work is devoted to investigation of C02 - H2S mixtures and C02 - H2S togeneous
radiolysis in the presence of powder sulphur., γ -irradiation of H2S - C02 mixtures has been
carred out at the static conditions at the range of temperature 320-450K in molibdenium glassy
ampoules. The doserate was determined by measuring hydrogen formation in irradiation
methane (G(H2) = 5,7) and it was equal to 3 104 gy/h. Radiolysis of C02 - H2S - S8 mixtures
have been carried out in silicon ampoules at the process of reagents mixing on electron
accelerator ELU - 4 at T ~ 320 K. Dozimetry of accelerated electrons (E = 4 MeV, I = I mkA)
was carried out measuring hydrogen formation in ethylen (G(H2) = 1,3) The rate of adsorbed
doze was 5 10(2) Gy/s . Detailes of ampoules purification and filling ampoules with C02 and H2S
have been given previously. At all experiments total gas pressure was 0.1 MPa.
