摘要:Abstract(#br)In the present study, reduced pressure distillation was performed to obtain distilled bio-oil from fast pyrolysis bio-oil. The experiments were completed at temperature 80 °C with a residual pressure of 15 mmHg. The distilled bio-oil yields of 61 wt% from reduced pressure distillation...
