High value-added utilization of lignin-rich CE and MSC were realized via pyrolysis.
•
Acetic acid of MSC was 30–38% lower than that of CE for bio-oil quality improvement.
•
Phenolic compounds enriched from CE and MSC fast pyrolysis reached 33.9% and 39.2%.
•
Biochar of MSC slow pyrolysis had a high mass yield and well-developed pore structure.
