Ethanol steam reforming over Ni and Ni–Cu catalysts

---

Abstract.
Steam reforming of ethanol over unsupported Ni and Ni–Cu catalysts was investigated. Ethanol and the
reaction intermediates like acetaldehyde and acetone are entirely converted into hydrogen and C1
products at 400 oC, while methane steam reforming and reversible water gas shift are the major
reactions at higher temperatures. The Ni–Cu catalyst exhibited stable performance during 40 h onstream
at 650 oC without apparent deactivation, but the Ni catalyst showed severe deactivation only
after 12 h on-stream due to heavy coke deposition. Filament carbon was mainly produced on the Ni
catalyst through the Boudouard reaction, whereas condensed carbon was formed on the Ni–Cu catalyst
by methane decomposition.
