Ammonia Synthesis Using Atomic Hydrogen Supplied From Silver-Palladium Alloy Membrane

Article Preview

Abstract:

Ammonia formation activity was studied on the Ru/(MgO-CeO2) catalyst loaded on a Ag-Pd hydrogen permeable membrane. The ammonia formation rate for the membrane reactor was more increased than that based on the conventional flow-type one due to the high reactivity of atomic hydrogen supplied from the Ag-Pd membrane. In addition, other on-site hydrogen generation type membrane reactor was also constructed, where the Ag-Pd alloy membrane was not only atomic hydrogen supplier but also an electrode for water electrolysis. Ammonia was effectively formed even at 373 K on this membrane reactor with the electrodeposited Ru metal powder catalyst.
