CatalystsHydrocarbon Reforming, Ammonia Cracking, and Water Gas Shift reaction catalysts to provide a good mix of high activity and high temperature durability. Available as catalyst pellets or 14-90 mesh catalyst granules to provide a good balance between low pressure-drop and high heat and mass transfer. | ||

Low Temperature Methanol Reformer / Water Gas Shift Catalyst: copper zinc alumina. For catalytic use at 200 C - 300 C. Also excellent for H2S sorption from gases, as a protective bed for membranes or any chemical process. Typical grain size = 14-90 mesh; shipping density = 1.34 g/cc. |
|
 |
Robust, Middle temperature reformer, WGS Catalyst Robust, Middle Temperature Methanol Reformer / Water Gas Shift Catalyst: copper zinc chromia ceria platinum alumina. For use at 250 - 450 C. Typical grain size = 14-90 mesh; shipping density = 1.31 g/cc |
|
|
Middle Temperature Hydrocarbon Reformer / High temperature Water Gas Shift Catalyst (iron, copper chromia ceria platinum). For use at 400 C - 700 C. Excellent for reforming, for Fischer Tropsch synthesis, and for high temperature water gas shift reactions. Durable in air. |
|
|
Iron Oxide-Based Water Gas Shift and Fisher Tropsch Catalyst (Iron Oxide, 2% copper, no Pt). A cheaper alternative to the above (no Pt content). For use at 400°C to 700°C. |
|
 |
Nickel- based catalyst for ammonia cracking, and for light hydrocarbon reforming at 750 C or higher. Also suitable for removing trace CO from hydrogen through the methane-formation reaction. 14-90 mesh. |

Hydrogen Removal - sorbers, getters, etc.Three options for hydrogen removal: An organic-based sorber, an oxidation catlyst, and a reversible Pd-coated metal. | ||

This hydrogen-removal, "getter" is made from DEB, palladium, and buckminsterfullerene. It's used for irreversible hydrogen removal from air, nitrogen, steam or inert atmospheres, at tempertures from -20°C to 50°C. Used in electronic packages, consumer, and industrial products where hydrogen would cause a safety or operational hazzard. This product is also used for nuclear transport. It's generally provided as pellets, but it can also provide it mixed into flex-seal to provide a paint-on coating. | |

1% Pt-CeO or Pt-alumina catalysts that remove unwanted H2 by combining it with oxygen. This is best done in the presence of air but the CeO version also works in nitrogen or inert gases. Uncoated catalyst works at 20°C to 600°C. Teflon coated catalyst works to -5°C. This is often used aboard submarines where battery-hydrogen is a safety hazzard. See our essay on low-temperature-hydrogen-removal. 3mm pellets. |

Pd-coated Niobium Screws and pellets Pd-coated niobium screws (4/40 thread by 1/4" long). Used for reversible hydrogen removal from inert gases, e.g. in space-based electronic packages at 50° to 200°C. Pd coated LaNi5 can be very effective in nickel metal hydride batteries or hydrogen storage. Hydrogen sorption is readily reversible. | |
