The increase in plastic products and disposal poses a severe environmental challenge because of their poor biodegradability and undesirable disposal by landfilling. Recycling is the best possible solution to the environmental challenges implemented by the plastic industry. Pyrolysis is a process that converts waste plastics into pyrolytic oil, and it can be used as fuel in a blended form. The viscosity and lubricity of the LDWP (low-density waste polyethylene) pyrolytic oil were lower than standard diesel. Capparis spinosa methyl ester (CME) is blended and experimented with to overcome the lubricity issue of pyrolytic oil. In this investigation, 5%, 10%, and 15% CME were blended with PD20 (20% LDWP oil + 80% diesel) blend on a volume basis. Experiments were conducted to examine the effects of CME on combustion, performance, and emissions using the combination of CME and PD20 blend tested at 0%, 25%, 50%, 75%, and 100% loading conditions. All three ternary mixtures showed enhanced combustion performance and increased NO and smoke emissions. Due to better combustion, the efficiency of the blend PCD10 (10% CME + 20% LDWP oil + 70% diesel) was higher than the PD20 blend and significantly closer to diesel. Hence, PCD10 is suggested as an alternative to diesel fuel.
塑料制品的增加及其处置方式对环境构成了严重挑战，因为它们的生物降解性差，通过填埋处置也不理想。回收利用是塑料行业应对环境挑战的最佳解决方案。热解是一种将废塑料转化为热解油的过程，它可以以混合形式用作燃料。低密度废聚乙烯（LDWP）热解油的粘度和润滑性低于标准柴油。卡波姆甲酯（CME）被混合并进行实验，以克服热解油的润滑性问题。在这项研究中，以体积为基础，将 5%、10%和 15%CME 与 PD20（20%LDWP 油+80%柴油）混合。使用 CME 和 PD20 混合在 0%、25%、50%、75%和 100%加载条件下进行实验，以检查 CME 对燃烧、性能和排放的影响。所有三种三元混合物都显示出增强的燃烧性能和增加的 NO 和烟雾排放。由于燃烧更好，混合燃料 PCD10（10%CME+20%LDWP 油+70%柴油）的效率高于 PD20 混合燃料，并且与柴油的接近程度显著提高。因此，PCD10 被建议作为柴油燃料的替代品。
