Industrialized Bio-oil Refining
Researchers at the University of Science and Technology of China have successfully converted sawdust, rice hull, corn stalk, and cotton stalk into bio-oil, through pyrolysis and re-processing. The technology has registered an oil producing capability of 60% for sawdust, and 50% for stalks, with a thermal value ranging between 16-18 MJ /kg. The effort has resulted in a self-heating pilot pyrolysis unit that can handle 120 kilograms of raw materials an hour. China enjoys rich agricultural residues amounting to 700 million tons a year, including stalks and hulls. The new technology makes converting raw biomasses into bio-oil possible. Bio-oil can be used as a direct fuel for oil-burning boilers or industrial kilns and furnaces. It also can serve as a substitute fuel for auto application after refining, or be made into a high value added chemical through separation and extraction. According to a briefing, the new technology allows a best single-unit handling capacity of 2 tons/hour for stalks (desirable for a stalk collection radius of 10km), and it takes about RMB 790 to produce a ton of bio-oil. A simple enhancement can raise the thermal value to 18-20 MJ /kg. If sold at RMB 1000 a ton, bio-oil makes a price only 43.2% of diesel oil, or 63.1% of heavy oil, though producing the same thermal value.
