Abstract

The kinetics of H₂ accumulation during the radiation-thermocatalytic decomposition of CH₄+ 2H₂O and 2CH₄+H₂O mixtures at T=300÷773 K (P_tot=1-12 atm) on the surface of aluminosilicate was studied. Doubling the relative concentration of methane in the reaction medium at T=773 K causes an increase in the yield of G(H₂) from 1.2 to 2.3 molecule/100 eV. Based on the results obtained on the heterogeneous radiolysis of methane and the CH₄+H₂O mixture, the following conclusions can be drawn that the efficiency of energy transfer in the Al–Si + CH₄ system is less than in the Al–Si + H₂O system, and the radiation-chemical yield of molecular hydrogen at heterogeneous radiolysis of methane in the presence of amorphous aluminosilicate at P_CH4≈1 atm, T=300÷773 K does not depend on temperature.
