%X Pyrolysis is one of thermochemical conversion to convert biomass into bio-oil. The higher energy content in bio-oil suggests its potential as a raw material in the production of energy, bio-fuels, and other chemicals. Pyrolysis of PKS and the chemicals released were studied using pyrolysis¨Cgas chromatography/mass spectrometry (Py-GC/MS) at 400-600ˇăC. Prior to pyrolysis, thermogravimetry experiments were carried out to monitor the degradation temperature of hemicellulose, cellulose, and lignin in the PKS. Degradation of hemicellulose occurred within a temperature range of 150-330ˇăC, whereas the cellulose was degraded in temperatures range between 330-400ˇăC. Degradation of lignin took place within a broad range of temperatures, which reached maximum at temperatures range of 200-500ˇăC. Based on the Py-GC/MS results, pyrolysis of PKS at 400ˇăC produced bio-oil that can be used as biofuel due to its high aromatic compounds but low carboxylic acids contents.
