Green and sustainable hydrogen production from methane and methane water mixture using aluminosilicate catalyst and gamma radiations
摘要
Hydrogen production was achieved by irradiating methane and methane-water mixtures at 300–873 K on aluminosilicate (Al–O–Si) surface with gamma radiations. Results with methane molecules were two times higher at 773 K i.e. an increase in G(H2) yields from 1.2 to 2.3 molecules/100 eV. The efficiency of energy transfer in Al–O–Si–methane system was less than in Al–O–Si–water system. The maximum amount of hydrogen produced was 65.0 × 1017 molecules/g at 10 atm methane pressure, 773 K temperature, 8 h and 1.2 Gy/s radiation dose. The amount of hydrogen produced is quite good and the results may be used on a pilot scale.
