The recovery of date palm leaflet waste (DPLW), generated by palms through anaerobic digestion (AD) technology, attracts more attention because of its many economic, social, and environmental benefits. In this study, a laboratory-scale experiment using a continuous stirring tank reactor digester (CSTR) operating in mesophilic semi-batch mode was conducted to evaluate experimental methane production, biodegradability, and organic loading rate (OLR). Besides, a theoretical estimate of methane was assessed using a Buswell–Neave equation. Moreover, three modified kinetic models (Logistic, Gompertz, and Richards) were applied to adjust the experimental methane production from the AD of DPLW. This study showed that the experimental methane yield and biodegradability of DPLW were 133 NmL CH₄/g VS and 33%, respectively, while the OLR was 2.76 kg VS/m³.d. The kinetic results showed that all three modified models (Gompertz, Richards, and Logistic) were useful for predicting methane production as a function of the added loads. However, the modified Gompertz model was the most suitable for experimental data, even under critical conditions. Indeed, the modified Gompertz model fitted the experimental methane production with an optimal correlation coefficient R² = 0.998.

棕榈通过厌氧消化（AD）技术产生的椰枣小叶废料（DPLW）的回收由于其许多经济，社会和环境效益而引起了更多关注。在这项研究中，使用以中温半间歇模式运行的连续搅拌釜反应器消化器（CSTR）进行了实验室规模的实验，以评估甲烷的实验产量，生物降解性和有机负荷率（OLR）。此外，使用Buswell-Neave方程评估了甲烷的理论估计值。此外，应用了三种改进的动力学模型（Logistic，Gompertz和Richards）来调节DPLW AD产生的甲烷的实验产量。这项研究表明DPLW的实验甲烷产率和生物降解性为133 NmL CH ₄/ g VS和33％，而OLR为2.76 kg V​​S / m ³ .d。动力学结果表明，所有三个修改的模型（Gompertz，Richards和Logistic）都可用于预测甲烷产量随负荷增加的变化。但是，即使在临界条件下，改进的Gompertz模型也最适合用于实验数据。确实，改进的Gompertz模型拟合了具有最佳相关系数R ²  = 0.998的实验甲烷生产。
