Abstract
- Abstract: The radiolysis of methane (0.7MeV electron beam) was studied as a function of its concentration at two doses: 5 and 20kGy. In both cases the G (–CH4) value raised with the increase of the substrate concentration. Thereby the yields observed at 20kGy are much lower, because of recombination processes. Results are also reported on the conversion of the gas mixture CH4:CO2:He=1:1:1 into synthetic gas (H2/CO) at 500°C, using two catalysts : (N5) and (N20), containing 5wt% Ni and 20wt% Ni, respectively, supported on γ-Al2O3. In an experimental series the catalysts (N5) and (N20) were treated by irradiation (4MGy dose) before use. The highest conversion yields (above 35%) were observed by implementation of N5 and N20 catalyst at 500°C under the influence of electron beam radiation. [Copyright &y& Elsevier]
