Natural gas reforming

WebSteam reforming is the most widespread process for the generation of hydrogen-rich synthesis gas from light carbohydrates. The feed materials natural gas, liquid gas or naphtha are endothermically converted with water steam into synthesis gas in catalytic tube reactors. Process heat as well as flue gas are used for the steam generation. WebH2 production via natural gas steam reforming-39.6% 60.4% 0.66 5.1 On a life cycle basis, for one MJ of fossil fuel consumed by the system, 0.66 MJ of hydrogen is produced (LHV basis). This reflects the fact that because natural gas is a non-renewable resource, more energy is consumed by the system than is produced.
