In this study, thorny bamboo (Bambusa stenostachya) and long-branch (B. dolichoclada) bamboo were integrated as feedstock to produce pyrolysis liquid (bio-oil) using fast pyrolysis technology, and the basic properties of the bio-oils were analyzed. Results showed that the higher heating value (HHV) of both bio-oils were 13.92 MJ/kg for thorny bamboo and 14.87 MJ/kg for longbranch bamboo, and both HHVs were relatively low for use as bioenergy. The bio-oils need to be reprocessed using upgrading technologies to promote the efficiency of energy utilization. However, both bio-oils were analyzed by gas chromatography mass spectrometry (GC-MS) and were shown to contain more than 80 different organic compounds with multifunctional groups. The major compounds in the bio-oil of long-branch bamboo were phenols with the largest proportion of >50%, and those of thorny bamboo included good distributions of phenols, carboxylic acids, and ketones. Both bio-oils are great potential resources beyond just a fossil fuel to provide various chemical compounds.
