Abstract
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(o)C. In the non-catalytic work, the maximum oil yield was obtained as 42% at 500(o)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.
