Steam reforming is generally the preferred process for hydrogen production.Particularly for portable hydrogen production, the requirement of an external heat source can be addressed through the advanced heat and mass transfer provided by microreactors. 

Two other hydrogen production methods, pyrolysis and aqueous reforming, have been explored for use in microreactors. Pyrolysis is the decomposition of hydrocarbons into hydrogen and carbon in water-free and air-free environments. ° If no water or air is present, no carbon oxides (e.g., CO or CO2) are...

A related effort is FORSiM (Fast Oxidation Reaction in Si-technology-based Microreactors) which is funded by the Dutch Technology Foundation and is a cooperative venture between the University of Twente and the Technical University of Eindhoven. The objective of this work is to build and operate the first microreactor for catalytic partial oxidation for small-scale and on-demand hydrogen production.61...

Dehydroganation of benzene at 473 K and propylene conversion aromatics at 773 K are used to compare the catalytic properties of [Zn]ZSM-5 and ZnZSM-5 in a pulse microreactor. The results shown in Table 3 indicate that the framework zinc catalyst (H[Zn]ZSM-5) does not exhibit activity for the hydrogenation reaction of benzene. In contrast, a hydrogenation product, cyclohexane (c-CeHiz), is observed over the cationic zinc catalyst (ZnZSM-5). The fact that an increase in the zinc content in ZnZSM-5 leads to an increase in the activity for the hydrogenation reaction suggests that...
