The present study aims to investigate the potential of Bauhinia purpurea seed (BPS) and waste medical plastic (WMP) as renewable fuels. Physicochemical and thermal studies show that BPS is a great raw material for pyrolysis because it has high calorific value, rich volatility, a lot of large functional groups, and favourable surface morphology. The activation energy was calculated using the KAS, FWO, Starink, and Friedman methods. Both RSM and ANN identified the optimal conditions for bio-oil production at a temperature of 550°C, a heating rate of 10 °C/min, a blend ratio of 70 % BPS (30 % WMP), and a particle size of 1 mm, with a generated bio-oil of 43.24 %. Notably, the predicted bio-oil yield (44.4 %) closely matched the experimental result (43.24 %). The bio-oil is obtained through pyrolysis, co-pyrolysis, and catalytic co-pyrolysis at optimum conditions. An analysis determined the suitability of bio-char as an activated carbon in catalytic pyrolysis.

紫荆花种子和废医用塑料的催化共热解用于可持续生物燃料生产：动力学分析和预测模型


本研究旨在调查紫荆花种子（BPS）和废医用塑料（WMP）作为可再生燃料的潜力。物理化学和热学研究表明，BPS具有高热值、丰富的挥发性、大量的大官能团和良好的表面形貌，是一种很好的热解原料。使用 KAS、FWO、Starink 和 Friedman 方法计算活化能。 RSM 和 ANN 都确定了生物油生产的最佳条件：温度为 550°C，加热速率为 10°C/min，混合比例为 70% BPS（30% WMP），粒径为 1 mm，生成的生物油为43.24%。值得注意的是，预测的生物油产量（44.4%）与实验结果（43.24%）非常吻合。在最佳条件下通过热解、共热解和催化共热解获得生物油。分析确定了生物炭作为催化热解活性炭的适用性。
