Slow pyrolysis of a pellet of pistachio waste was studied using a macro-thermogravimetric analysis. Experiments were conducted at different heating rates (5, 10, and 15 K/min), measuring the evolution of mass weight loss and CO release. Based on a dimensionless number analysis, a numerical model was formulated, comprising heat and mass balances. A kinetic expression for the release of CO was proposed. Additionally, a 3-E (environmental, exergetic, and energetic) analysis for the processing of 20 kg/h of bio-waste (case study) was applied. Experimental results showed that biochar and gas yields decreased with an increase in the heating rate (43 to 36% and 28 to 24%, respectively), while the bio-oil yield increased (29 to 40%). The slow pyrolysis model presented a good agreement with experimental results of weight loss. Furthermore, a comparison with the contracting volume model showed that internal heat transport should control the global process. The proposed kinetic model for CO release showed a good fit to experimental data, where activation energy values were 29.88 (5 K/min), 17.44 (10 K/min), and 28.79 kJ/mol (15 K/min). Finally, from the 3-E analysis and the experimental results, it can be suggested that an increase in the heating rate resulted in a higher pyrolysis exergetic efficiency (70%). It is due to an increase in the bio-oil yield with high-energy content.

使用宏观热重分析研究开心果废料颗粒的缓慢热解。以不同的加热速率（5、10 和 15 K/min）进行实验，测量质量失重和 CO 释放的演变。基于无量纲数分析，制定了一个数值模型，包括热量和质量平衡。提出了释放 CO 的动力学表达式。此外，对处理 20 公斤/小时的生物废物（案例研究）进行了 3-E（环境、运动和能量）分析。实验结果表明，随着加热速率的增加，生物炭和气体的产率降低（分别为 43% 至 36% 和 28% 至 24%），而生物油产率增加（29% 至 40%）。慢热解模型与失重实验结果吻合较好。此外，与收缩体积模型的比较表明，内部热传输应该控制全局过程。所提出的 CO 释放动力学模型显示出与实验数据的良好拟合，其中活化能值为 29.88 (5 K/min)、17.44 (10 K/min) 和 28.79 kJ/mol (15 K/min)。最后，从 3-E 分析和实验结果可以看出，加热速率的增加导致更高的热解火用效率（70%）。这是由于高能量含量的生物油产量增加。从 3-E 分析和实验结果可以看出，加热速率的增加导致更高的热解热能效率（70%）。这是由于高能量含量的生物油产量增加。从 3-E 分析和实验结果可以看出，加热速率的增加导致更高的热解热能效率（70%）。这是由于高能量含量的生物油产量增加。
