Reforming reactions for hydrogen

The catalytic combustor provides heat for the endothermic reforming reaction and the vaporization of liquid fuel. The endothermic reforming reaction is carried out in a parallel flow-type micro-channel of the reformer unit. It is well known that the methanol steam reforming reaction for hydrogen production over the Cu/ZnO/AbOs catalyst involves the following reactions [10]. Eq. (1) is the algebraic summation of Eqs. (2) and (3).

The demonstration test of the coupling of the steam reforming system to the HTTR will contribute to the technical solution of all other hydrogen production system because basic system arrangement and endothermic chemical reactions for hydrogen production are similar. 

Finally, the reactions for hydrogen production are often quite endothermic (reforming reactions) or exothermic (e.g. CPO). The temperature control is thus quite important because a decrease in temperature on the membrane surface leads to a decrease in hydrogen flux through the membrane while an increase in temperature could result in crack on the membrane surface with a consequent decrease of permselectivity (and thus deteriorating the MR performance). The heat management and temperature control in PBMRs is quite... 

The reaction for hydrogen production via the hydrogen sulfide reforming of methane is as follows [21] ... 

Mixtures of CO—H2 produced from hydrocarbons, as shown in the first two of these reactions, ate called synthesis gas. Synthesis gas is a commercial intermediate from which a wide variety of chemicals are produced. A principal, and frequendy the only source of hydrogen used in refineries is a by-product of the catalytic reforming process for making octane-contributing components for gasoline (see Gasoline and OTHER MOTOR fuels), eg.
