The yield of levoglucosan (LG : a kind of anhydrosugar) from wood particles by pyrolysis was studied using an infrared-ray furnace under various heating rates.
A slight reduction of pressure was found to increase the yield of levoglucosan. The increase of heating rate resulted in an increase in the yield of levoglucosan and a decrease in the yield of solid product, as was the case for the reduction of pressure. However, at an extremely high heating rate, the yield of levoglucosan decreased. As a result of pyrolysis of Karamatsu under 88 kPa, the maximum yield of levoglucosan was obtained at a heating rate of nearly 1.3 K/s.
