Bio-coal: A renewable and massively producible fuel from
Properties of bio-coal. The bio-coal preparation process is illustrated in Fig. 1A. Briefly, the renewable biomass (e.g., rice husk, saw dust, corn stalk, etc.) was first fast pyrolyzed at 500°C under anaerobic atmosphere to produce bio-oil and biochar. Then, the bio-oil was distilled under air atmosphere from room temperature to approximately ...
