Plastic waste poses a significant environmental challenge due to its non-biodegradable nature and accumulation in landfills. Converting plastic waste into usable fuel could offer a promising solution for mitigating these issues while addressing the emission-related challenges of diesel engines. This study investigates the impact of plastic waste oil (WPO) obtained through pretreatment and catalytic pyrolysis, blended with acetone-butanol-ethanol (ABE) and diesel fuel, on diesel engine. The aim was to evaluate how these blends affect gaseous emissions, organic compounds, and particle-bound carbon, focusing on their potential to reduce harmful pollutants compared to pure diesel fuel. The results indicated that the ABE5W15D blend significantly reduced smoke and CO emissions by 35.7 % and 17.43 %, respectively, with a slight decrease in HC emissions. However, the ABE20W blend showed elevated NOx levels due to higher ignition delay and increased cylinder pressure. Compared to pure diesel (D100), ABE10W10D and ABE5W15D blends reduced total polycyclic aromatic hydrocarbons (PAHs) emissions by 26.8 % and 37.4 %, respectively. Naphthalene was the dominant PAH, remarkably increasing with W20D use, while longer-chain alkanes associated with lubricant oil had higher W20D emissions. The ABE5W15D blend notably reduced organic carbon (OC) emissions by approximately 38.26 % compared to D100. ABE20D exhibited lower elemental carbon (EC) emissions than D100, although it had higher EC than OC. The W20D blend resulted in larger particle diameters, whereas ABE10W10D showed lower particle counts in the 7–15 nm range. In conclusion, blending plastic waste oil with ABE and diesel fuel can effectively mitigate certain pollutants, depending on the blend composition.

以塑料废油、丙酮-丁醇-乙醇和柴油混合物为燃料的柴油发动机的排放和颗粒特性的实验研究


塑料垃圾由于其不可生物降解的性质和在垃圾填埋场的积累，构成了重大的环境挑战。将塑料废物转化为可用的燃料可能为缓解这些问题提供一种有前途的解决方案，同时解决柴油发动机的排放相关挑战。本研究调查了通过预处理和催化热解获得的塑料废油 （WPO），与丙酮-丁醇-乙醇 （ABE） 和柴油混合，对柴油发动机的影响。目的是评估这些混合物如何影响气体排放、有机化合物和颗粒结合碳，重点关注与纯柴油燃料相比，它们减少有害污染物的潜力。结果表明，ABE5W15D混合物分别显著降低了 35.7% 和 17.43% 的烟雾和 CO 排放，HC 排放量略有减少。然而，由于点火延迟较高和气缸压力增加，ABE20W 混合物的 NOx 水平升高。与纯柴油 （D100） 相比，ABE10W10D 和 ABE5W15D 混合物的多环芳烃 （PAH） 总排放量分别减少了 26.8% 和 37.4%。萘是主要的 PAH，随着 W20D 的使用而显着增加，而与润滑油相关的长链烷烃具有更高的 W20D 排放。与 D100 相比，ABE5W15D 混合物显著减少了约 38.26% 的有机碳 （OC） 排放。ABE20D 的元素碳 （EC） 排放量低于 D100，尽管它的 EC 高于 OC。W20D 混合物产生的粒径较大，而 ABE10W10D 的颗粒粒数在 7–15 nm 范围内较低。总之，将塑料废油与 ABE 和柴油混合可以有效减轻某些污染物，具体取决于混合物的成分。
