In this study, the catalytic pyrolysis of waste furniture sawdust in the presence of ZSM-5, H-Y and MCM-41 (10 wt % of the biomass sample) was carried out in order to increase the quality of the liquid product at the various pyrolysis temperatures of 400, 450, 500 and 550 degrees C. In the non-catalytic work, the maximum oil yield was obtained as 42% at 500 degrees C in a fixed-bed reactor system. In the catalytic work, the maximum oil yield was decreased to 37.48, 30.04 and 29.23% in the presence of ZSM-5, H-Y and MCM-41, respectively. The obtained pyrolysis oils were analyzed by various spectroscopic and chromatographic techniques. It was determined that the use of a catalyst decreased acids and increased valuable organics found in the bio-oil. The removal of oxygen from bio-oil was confirmed with the results of the elemental analysis and gas chromatography-mass spectrometry.
