4. Pure ethanol steam reforming

A large number of studies have been carried out on the steam reforming of pure ethanol. Even if the results cannot be directly extrapolated to bioethanol, which contains various impurities, these studies have the advantage of laying down the main rules and proposing various solutions for increasing hydrogen yield.

4.1 General information on steam reforming of alcohols

Alcohols are highly reactive molecules that decompose more easily than hydrocarbons on metal catalysts. In the presence of water, the general equation for the steam reforming of alkanols is :
