Abstract
Hydrogen fuel production from methane gas is studied by using the plasma reforming technology using dielectric barrier discharge (DBD) which is eco-friendly method without generating harmful gas of carbon monoxide or carbon dioxide. Hydrogen production properties were evaluated in velocity control of gas flow due to the reactor gaps and gas convection time during DBD plasma reforming. High hydrogen production was attainable by using the plasma reactor having wide gap at higher input power region. Moreover, it was found that hydrogen production was highly reformed at lower input power by making use of the convection effect of induced gas flow by the DBD plasma generated in airtight reactor filled up with the gas.
