The recyclability of a coked ethanol steam reforming catalyst (Co/Al₂O₃) is studied over several cycles. Oxidative regeneration burns coke, however some of the cobalt is oxidized. H₂ produced during reforming promotes self-reactivation, restoring catalyst activity. The regeneration leads to the redispersion of smaller cobalt particles as a result of the Kirkendall effect.

乙醇蒸汽重整反应-再生循环的Operando XAS / Raman / MS监测†

研究了焦化乙醇蒸汽重整催化剂（Co / Al ₂ O ₃）的可循环性。氧化再生燃烧焦炭，但是其中一些钴被氧化。重整过程中产生的H ₂促进自活化，恢复催化剂活性。由于柯肯德尔效应，再生导致较小的钴颗粒重新分散。
