Preparing Levoglucosan Derived from Waste Material by Pyrolysis

Waste newspaper and waste cotton were pyrolyzed in tubular furnace pyrolysis equipment. This experiment is directed to the influence of pyrolysis temperature on yield of levoglucosan and other pyrolysis products from waste material. The results show that levoglucosan yield is correlate to pyrolysis oil yield. The highest yield of levoglucosan can be obtained when the pyrolysis temperature was around 420°C in waste newspaper and 420°C in waste cotton. Bio-oil, gas, and char yields of different temperature were also determined. The HPLC analysis shows main composition is acetic acid in aqueous phase while relatively large proportion is levoglucosan in nonaqueous phase.
