The main aim of this work was to investigate the suitability of a KI/KIO impregnated hydroxyapatite (HAP) catalyst derived from natural phosphate rocks for biodiesel production. This study evaluated the effect of impregnation concentrations (1-6% /) on the catalyst performance in biodiesel production. The biodiesel was produced from waste cooking oil (WCO) under simultaneous esterification-transesterification reactions at 60 °C for 6 h. The results showed that the biodiesel yield increased by increasing impregnation concentration and the maximum yield (91.787%) was achieved at an impregnation concentration of 5% /. The KI/HAP catalyst showed better performance (91.78% biodiesel yield, 59.1% FAME yield and surface area of 13.513 m/g) as compared to the KIO/HAP catalyst (90.07% biodiesel yield, 55.0% FAME yield and surface area of 10.651 m/g).
这项工作的主要目的是研究一种从天然磷矿石衍生的碘化钾/高碘酸钾浸渍羟基磷灰石（HAP）催化剂在生物柴油生产中的适用性。本研究评估了浸渍浓度（1-6% /）对催化剂在生物柴油生产中性能的影响。生物柴油是由废食用油（WCO）在 60°C 下通过同时酯化-酯交换反应 6 小时制备的。结果表明，随着浸渍浓度的增加，生物柴油的产率增加，在浸渍浓度为 5%时达到最大产率（91.787%）。与高碘酸钾浸渍羟基磷灰石（KIO/HAP）催化剂（90.07%生物柴油产率、55.0%脂肪酸甲酯（FAME）产率和 10.651 m/g 的表面积）相比，碘化钾浸渍羟基磷灰石（KI/HAP）催化剂具有更好的性能（91.78%生物柴油产率、59.1% FAME 产率和 13.513 m/g 的表面积）。
