Può essere considerato il processo più comune e diffuso al mondo. Infatti viene impiegato per la produzione del 50% dell’idrogeno prodotto a livello mondiale. Similmente al processo di gassificazione, lo steam reforming fa reagire il vapore acqueo, a temperature fra gli 800-1100 °C, per produrre gas di sintesi, il syngas. Come si può vedere nello schema, talvolta può essere necessario ricorrere ad una desolforazione, per eliminare le quantità di zolfo presenti nel combustibile di partenza, convertendolo in acido solforico (H2S). Il processo si può dividere in tre fasi principali:

process can be considered the most common and widespread in the world. in fact is used for the production of 50% of the hydrogen produced worldwide. similarly to the process of gasification, steam reforming is reacted water vapor, at temperatures between 800-1100 ° C, to produce synthesis gas, the syngas. as you can see in the diagram,sometimes it may be necessary to resort to a desulfurization, to eliminate the amount of sulfur present in the fuel starting, converting it into sulfuric acid (H2S). the process can be divided into three main phases:
