TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Material: The heat transfer material is water. The first material is a fuel processor catalyst, preferably a catalytic partial oxidation (CPO), high temperature shift (HTS) or low temperature shift (LTS) catalyst. The LTS catalyst is at least as active as Fe2O3. It comprises copper, nickel (Ni), iron, chromium, zinc, cobalt, platinum (Pt), palladium (Pd), rhodium (Rh), ruthenium (Ru), iridium, cupric oxide (CuO) or cuprous oxide. The second material is a desiccant and comprises zeolite (preferably), silicon oxide, aluminum oxide (Al2O3) or clay. The third material comprises zinc oxide (ZnO), Al2O3, zirconium oxide (ZrO), or iron oxide. The first and third materials comprise a catalytic composite comprising less than 60 or 5-15 wt.% of the third material. The fourth material comprises ZnO, ZrO, or iron oxide. The fifth material comprises Pt, Ni, Pd, Rh or Ru.Preferred Component: The exothermic reaction causes the heat transfer material to desorb from the second material. It can be an oxidation or a reduction reaction. The first material is disposed on a third material with a load of 5-30 or 10-60 wt.%, and is coated on the second material. It is capable of catalyzing oxidation of carbon monoxide. The second material is present in an amount to prevent the composition from sintering when the first material is in the reduced state and is exposed to air. The first and second materials are formed into granules having a cross-sectional dimension of 1/8 inch. They are in a weight ratio of 1:1-1:10, preferably 1:1-1:5. The catalytic composite and the second material are in weight ratio of 1:1. The catalytic composite comprises a fourth material, and a fifth material. It comprises less than 50 or 20-30 wt.% of the fourth material. The fifth material is capable of sorbing hydrogen and forming hydrogen atoms. The first material has a reduced state, an oxidized state, and a sintering temperature. The second material is present in an amount to prevent the composition from reaching the sintering composition when the first material has a starting temperature of less than 100 degreesC and is in the reduced or oxidized state and is exposed to a flow of 4 L/min of air or 100 standard L/min of hydrogen. The reformer is devoid of a high-temperature shift catalyst. The desiccant material has a starting temperature less than 100 degreesC and is present in an amount to prevent the cuprous oxide from reaching 400 degreesC when 20 kg of granules are exposed to a water-saturated flow of 100 standard L/minute of hydrogen at a temperature less than 300 degreesC. EXAMPLE - CuO/ZnO/Al2O3 catalyst pellets (LK821-2), and a Type X (sodium form zeolite, Siliporite G5, 10 Angstrom) were mixed in a 1:1 weight ration and milled into a powder in an oxygen-free atmosphere. The powder was thoroughly mixed, and the sieve fraction up to 0.5 mm was placed in a pelletizer and formed into cylindrical pellets of 1/8-inch diameter and 1/8 inch length.
