Reactions that are taking place in the reformer are as follows: 2CH4 + O2 + CO2 3H2 + 3CO + H2O. To obtain pure hydrogen at the end, pressure swing adsorption systems or caustic absorption gas scrubbers are used. SMR (steam methane reforming) method is considered to be the most efficient and feasible procedure. HWko__ Fossil fuel reforming does not eliminate carbon dioxide release into the atmosphere but reduces the carbon dioxide emissions and nearly eliminates carbon monoxide emissions as compared to the burning of conventional fuels due to increased efficiency and fuel cell characteristics. Zero carbon emissions 'turquoise' hydrogen is produced by one-step methane pyrolysis of natural gas. Hydrogen deletes little tailpipe pollution and is considered less of a pollutant. +
