Abstract

Rh/CeO₂-ZrO₂ catalysts with various CeO ₂/ZrO₂ ratios have been applied to H₂ production from ethanol steam reforming at low temperatures. The catalysts all deactivated with time on stream (TOS) at 350°C. The addition of 0.5% K has a beneficial effect on catalyst stability, while 5% K has a negative effect on catalytic activity. The catalyst could be regenerated considerably even at ambient temperature and could recover its initial activity after regeneration above 200°C with 1% O₂. The results are most consistent with catalyst deactivation due to carbonaceous deposition on the catalyst.
