摘要

•High bio-oil yield of low O content by cascade biomass catalytic fast pyrolysis (CFM).•Acid ZrO2/ZSM-5-attapulgite catalyzes CFP; base K-(USY-attapulgite) further upgrades.•Micro-spectroscopy to study deactivation modes and reversibility upon regeneration.•Coke in ZrO2/ZSM-5-attapulgite causes acid site poisoning.•K-(USY-attapulgite) deactivated irreversibly, damaging structure and basicity.
