- •
Coke formation is the main cause of catalyst deactivation in bio-oil hydrodeoxygenation.
- •
Quantity and species of coke on spent catalysts determine possibility of catalyst regeneration.
- •
Oxygenated compounds and graphitic carbon contained in coke deactivate catalysts.
- •
Cu reduces coke formation for Ni/HZSM-5 catalyst.
