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.
在本研究中，为了在400、450、500和550℃的不同热解温度下提高液体产物的质量，在ZSM-5、H-Y和MCM-41（占生物质样品的10 wt%）存在的情况下对废弃家具锯末进行了催化热解。在非催化实验中，在固定床反应器系统中500℃时获得的最大油产率为42%。在催化实验中，在ZSM-5、H-Y和MCM-41存在的情况下，最大油产率分别降至37.48%、30.04%和29.23%。通过各种光谱和色谱技术对获得的热解油进行了分析。结果表明，使用催化剂减少了生物油中的酸，并增加了其中发现的有价值的有机物。元素分析和气相色谱-质谱联用的结果证实了生物油中氧的去除。
