Conclusions
The first reaction zone (Tshoulder − Tonset(hc)) of lignin-rich biomass CE and MSC was much narrower than other common biomass. Maximum yield of bio-oil derived from fast pyrolysis of CE (58.13 wt%) and MSC (45.01 wt%) were obtained at 600 °C using quartz tube reactor and the phenolic compounds reached 33.9% and 39.2%, respectively. Acetic acid yield of MSC from fast pyrolysis was 30–38% lower than that of CE, suggesting that mushroom cultivation process was conductive to improve bio-oil quality. Biochar of MSC from slow pyrolysis had a high mass yield (44.38 wt%) with well-developed pore structure
