Converting waste lubricating oil into diesel-like liquid fuels using pyrolysis presents a dual solution, addressing environmental pollution while offering a viable response to the fossil energy crisis. However, achieving high-quality fuel with a substantial yield necessitates the utilization of highly active and cost-effective catalysts. We report the development of Fe-Ni nanocatalysts, synthesized using a green approach and supported on TiO, as a promising strategy for converting waste lubricating oil into premium-grade diesel-like fuel. To ensure efficient and effective pyrolysis processes, tailoring the synthesis parameters of these nanocatalysts is indispensable. In this study, we investigate the effect of design parameters on nanocatalyst synthesis, such as the concentrations of pre-catalysts and reducing agents, reducing time, and the amount of support material, and evaluate their impact on the quality and quantity of pyrolysis products. Through optimization of the synthesis process, a high quality diesel-like fuel with a product yield of about 54% at a mild reaction temperature of 400 °C was obtained. This study highlights the critical role of nanocatalysis in addressing persistent environmental and energy challenges while showcasing the potential of green nanocatalysts in sustainable waste-to-energy conversion processes.
利用热解将废润滑油转化为类似柴油的液体燃料提供了一种双重解决方案，既能解决环境污染问题，又能对化石能源危机做出可行的应对。然而，要获得高产率的高质量燃料，就需要使用高活性且经济高效的催化剂。我们报道了采用绿色方法合成并负载在TiO上的Fe-Ni纳米催化剂的开发，这是将废润滑油转化为优质类似柴油燃料的一种有前景的策略。为确保热解过程高效有效，调整这些纳米催化剂的合成参数必不可少。在本研究中，我们研究了设计参数对纳米催化剂合成的影响，如前体催化剂和还原剂的浓度、还原时间以及载体材料的用量，并评估它们对热解产物质量和产量的影响。通过优化合成过程，在400°C的温和反应温度下获得了产率约为54%的高质量类似柴油的燃料。这项研究突出了纳米催化在应对持续的环境和能源挑战中的关键作用，同时展示了绿色纳米催化剂在可持续的废物到能源转化过程中的潜力。
