Research Abstract

Pyrolysis method was investigated for the selective recovery of tar which can be converted into valuable chemicals easily. As a result, furan was recovered from xylan in woody biomass with a high yield suppressing devolatilization of lignin by the two-step pyrolysis. On the other hand, extracted lignin was converted into the resin materials by pyrolysis.
