文摘
- •
Deactivation mechanism of CaO on V2O5-WO3/TiO2 catalysts are studied.
- •
CaO can passivate bulk tungsten species and surface acid sites of fresh catalyst.
- •
CaWO4 formation occurs after the high content of CaO is introduced.
- •
HEDP regeneration shows excellent removal rate of CaO but low V2O5 loss.
