Abstract In this work, a non-edible seed Neem (Azadirachta indica) was used to find out it’s potential to produce fuels and chemicals using thermo-catalytic pyrolysis. The physiochemical characterization confirmed the seed’s bioenergy potential. Thermal and catalytic pyrolysis were carried out at optimum conditions (500 °C temperature, 80 °C min−1 heating rate, 0.5 mm particle size and 80 mL min−1 nitrogen gas flow rate) which produced maximum liquid yield (49.53 wt. % at thermal, 54.06 wt. % and 52.08 wt. % for K2CO3 and Zeolite respectively at Biomass/Catalyst ratio 8:1). The comparative study of thermal and catalytic pyrolytic liquid confirmed that the yield as well as fuel properties of pyrolytic liquid were enhanced with the use of catalysts. It was also noticed that the energy content of gases increased with increasing pyrolysis temperature. Further, with increase in pyrolysis temperature, the amounts of hydrogen and hydrocarbons increased significantly, but at the same time, the formation of carbon dioxide was reduced.

不可食用印楝种子向清洁燃料和化学品的热催化转化

摘要 在这项工作中，一种非食用种子印楝 (Azadirachta indica) 被用于发现其利用热催化热解生产燃料和化学品的潜力。理化特性证实了种子的生物能源潜力。热解和催化热解在最佳条件下进行（500 °C 温度、80 °C min-1 加热速率、0.5 mm 粒径和 80 mL min-1 氮气流速）产生最大液体产率（49.53 wt. %生物质/催化剂比例为 8:1 时，K2CO3 和沸石分别为 54.06 重量％和 52.08 重量％)。热解液和催化热解液的对比研究证实，使用催化剂可以提高热解液的产率和燃料性能。还注意到气体的能量含量随着热解温度的升高而增加。
