Efficiency of steam methane reforming

WebSteam reforming is a means of producing hydrogen from a light hydrocarbon using high temperature steam (700-1000°C) at moderate pressures (15-30 bars). It is one of … 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.
