“…Catalytic cracking of ammonia generates a CO 2 -free mixture containing 75% hydrogen. However, ammonia is toxic and poses a problem of generating nitrogen oxides during catalytic combustion of the cell effluent [6]. Methanol, which is mainly prepared by syn-gas conversion, has a favorable H:C ratio of 4, is largely distributed and is available in abundance.…”

“…Research has continued on methanol steam reforming over different catalysts such as:Cu-Mn, Cu-Cr-Zn, CuNi-Fe, Cu-Cr, Cu-Co, Fe-Cr-Ni and Cu-ZnO-Al 2 O 3 [3][4][5][6]. Natural gas, methane, ethanol, propane and butane can also be used as fuels for hydrogen production [7][8][9][10][11][12][13][14][15]. To facilitate the transition between the internal combustion engine and fuel cell vehicles, hydrocarbons like gasoline and diesel have to be used to produce hydrogen.…”

Steam reforming of isobutane on a 0.5% Pt-Ce 0.8 Gd 0.2 O 1.9 catalyst was carried out from 300 to 700°C under integral conditions with a gas hourly space velocity (GHSV) of 12,000 h )1 . The major products were H 2 , CO 2 , CO and CH 4 . The other products produced were ethane, ethylene, propane and propylene with a total molar composition of less than 1.5%. A complete conversion of isobutane was achieved at 700°C, Kinetic data was obtained by changing the partial pressure of the reactants and the temperature under differential conditions with a GHSV of 55,400 h )1 . This was done after observing stable isobutane steam reforming for 160 h and under conditions where the mass transfer limitations were insignificant. An empirical LangmuirHinshelwood type model that best fit the kinetic data available was developed.

Hydrogen production using ethanol and Fe 2 O 3 /support in a redox cycle was investigated. The composites were prepared by impregnation of Al 2 O 3 and SiO 2 with Fe(NO 3 ) 3 , with different proportions of iron, i.e. 10, 30 and 50 wt.%, calcinated at 450 • C and characterized by Mössbauer spectroscopy, XRD, SEM, BET and TG. The redox cycle to produce and/or store hydrogen is a two step process (1) initially the ethanol is used to reduce the iron oxide to Fe • ; (2) and when H 2 is needed, Fe • reacts with H 2 O to produce CO-free hydrogen, and the iron oxide is reduced again to Fe • making this system cyclic. After the reactions it was interesting to observe that ethanol can directly reduce the iron oxide to produce metallic iron, with carbon deposition and iron-carbon as side product. Preliminary results indicate that it is possible to perform multiple redox cycles with the supported iron oxide without deactivation.
