英文摘要	Lignocellulosic biomass is a renewable source of energy which can be harnessed to produce biofuels maintaining the carbon neutrality in the atmosphere. Thus, in this work, results of the pyrolysis of solid wastes of Polyalthia Longifolia (PL) leaves have been reported over a range of temperature from 450 °C to 600 °C at an interval of 50 °C. All experiments have been carried out three times in order to ensure repeatability and/or reduce measuring uncertainties; and the average values along with their standard deviation values are presented. The pyrolytic products have been thoroughly characterized by several advanced characterization techniques such as FTIR, GCMS, NMR, XRD, SEM, TGA, etc. as applicable to different products in addition to their physical and fuel properties. Further, the physical and fuel properties are reported for both individual organic and aqueous phases after separating liquid pyrolysis product; as well as based on raw liquid product obtained by pyrolysis before separating into organic and aqueous phases. The average higher heating value of organic phase bio-oil is varying in the range 21.74–24.28 MJ/kg for different pyrolysis temperatures. The moisture content of organic phase bio-oil varies between 0.36 mass % and 8.88 mass % over the temperature range of this study. The pH of organic phase bio-oil is in the range of 5.80 to 6.04 which indicate that the bio-oil is only marginally acidic; and further this range of pH is far better than their counterparts of open literature. From the GCMS analysis of bio-oil samples, it is found that phenol, 2,6-dimethoxy (syringol) is present with highest area % of 22.71 for the case of 600 °C pyrolysis temperature. Finally, the bio-oils produced from the pyrolysis of PL leaves are of good quality in terms of moderately large HHV, pH and low moisture content. © 2020 Elsevier Ltd
