In this study, a heterogeneous catalyst prepared by pyrolysis of waste cork (Quercus suber) was used for the transesterification of waste cooking oil (WCO). Physicochemical properties of the synthesized biochar catalyst were studied using BET, SEM, FTIR, and XRD. The experiment results demonstrate that heterogeneous catalyst synthesized at 600 °C showed maximum fatty acids methyl esters (FAMEs) conversion (98%) at alcohol:oil (25:1), catalyst loading (1.5% w/v) and temperature 65 °C. Biodiesel produced from WCO (Canola oil) mainly composed of FAMEs in following order C18:1 > C18:2 > C16:0 > C18:0 > C20:0. Properties of produced biodiesel were analysed as cetane number (CN) 50.56, higher heating value (HHV) 39.5, kinematic viscosity (ʋ) 3.9, and density (ρ) 0.87.
在这项研究中，使用废软木（栓皮栎）热解制备的非均相催化剂用于废食用油（WCO）的酯交换反应。使用 BET、SEM、FTIR 和 XRD 研究了合成生物炭催化剂的物理化学性质。实验结果表明，在 600°C 下合成的非均相催化剂在醇油比（25:1）、催化剂负载量（1.5%w/v）和温度 65°C 下显示出最大的脂肪酸甲酯（FAMEs）转化率（98%）。由 WCO（菜籽油）生产的生物柴油主要由以下顺序的 FAMEs 组成：C18:1 > C18:2 > C16:0 > C18:0 > C20:0。分析了所生产生物柴油的特性，包括十六烷值（CN）50.56、高热值（HHV）39.5、运动粘度（ʋ）3.9 和密度（ρ）0.87。
