This work studied the optimal conditions for pyrolysis of Prosopis juliflora wood in fixed-bed tubular reactor. The optimal conditions are measured by performing pyrolysis experiment with respect to wood properties such as particle size, moisture and pyrolysis condition such as, temperatures, heating rates. Higher solid yield (36.8%) was recorded for a slower heating rate of larger particle size at lower temperatures. Further, higher liquid yield (38.3%) was observed while maintaining high heating rate and temperature. It is observed that with increase in particle size, the yield of char and gas decreases and bio-oil increases. The literature reported biomass pyrolysis kinetic model is validated for Prosopis juliflora wood. The kinetic models are able to predict the performance of fixed-bed tubular reactor in terms of pyrolysis product properties. The validated kinetic model may be used for the design of commercial fixed bed pyrolysis reactor to process Prosopis juliflora wood.
本工作研究了在固定床管式反应器中热解刺槐木材的最佳条件。通过对木材特性（如粒径、水分）和热解条件（如温度、加热速率）进行热解实验来测量最佳条件。在较低温度下采用较慢的加热速率和较大粒径可获得更高的固体产率（36.8%）。进一步，在保持较高加热速率和温度的情况下，观察到更高的液体产率（38.3%）。观察到随着粒径的增加，焦产率和气体产率降低，而生物油产率增加。验证了文献报道的生物质热解动力学模型在刺槐木材上的适用性。这些动力学模型能够预测固定床管式反应器在热解产物特性方面的性能。经过验证的动力学模型可用于设计商业固定床热解反应器以处理刺槐木材。
