Abstract

Biodiesel stands out as a promising contender in the quest for renewable energy solutions, offering a greener alternative to traditional fossil fuels. Derived primarily from the transesterification of vegetable oils or animal fats, biodiesel offers an eco-friendly energy avenue with a minimized carbon footprint. Catalysts are central to the success of this process, which significantly enhance yield rates. Geopolymers, traditionally associated with construction applications due to their inorganic nature, have been derived from aluminosilicate sources activated using alkaline solutions. However, recent advancements spotlight geopolymers in a new light, emphasizing their prospective role as nanocatalytic agents for biodiesel synthesis. This paradigm shift suggests improved production efficiency and an innovative method of repurposing industrial waste. This study centers on the pioneering application of geopolymers, fortified with magnetite, as potent heterogeneous catalysts for biodiesel generation from soybean and safflower oils. By leveraging a meticulously crafted geopolymer matrix—consisting of metakaolin, sodium hydroxide, and magnetite—this research replaced traditional catalysts with this advanced nanostructured geopolymer variant in the biodiesel methylation process. The research delved deep to ascertain the prime synthesis conditions. Furthermore, utilizing cutting-edge machine learning methodologies provided an analytical lens to navigate the extensive experimental data, thereby fine-tuning the optimization trajectory. One of the salient takeaways from this research is the validation that geopolymer catalysts, rooted in kaolinite, can be ingeniously tailored to ensure elevated biodiesel yields across a spectrum of oil sources, underscoring their unparalleled efficiency and versatility in the biofuel domain.

在人工智能辅助下使用可磁化的土工聚合物作为异相催化剂纳米复合材料合成生物柴油
在寻求可再生能源解决方案的过程中,生物柴油脱颖而出,成为前景广阔的竞争者,为传统化石燃料提供了更环保的替代品。生物柴油主要来源于植物油或动物脂肪的酯交换反应,是一种碳足迹最小的环保能源。催化剂是这一过程取得成功的关键,可显著提高产量。土工聚合物由于其无机性质,传统上与建筑应用有关,它是从使用碱性溶液活化的硅酸铝中提取的。然而,最近的研究进展从一个新的角度聚焦了土工聚合物,强调了它们作为纳米催化剂在生物柴油合成中的潜在作用。这种模式的转变提高了生产效率,并为工业废物的再利用提供了一种创新方法。本研究的中心内容是开创性地应用添加了磁铁矿的土工聚合物作为强效异相催化剂,从大豆油和红花油中生成生物柴油。这项研究利用由偏高岭土、氢氧化钠和磁铁矿组成的精心制作的土工聚合物基质,在生物柴油甲基化过程中用这种先进的纳米结构土工聚合物变体取代了传统催化剂。该研究深入探讨了最佳合成条件。此外,利用最先进的机器学习方法提供了一个分析透镜来浏览大量实验数据,从而对优化轨迹进行微调。这项研究的突出成果之一是验证了植根于高岭石的土工聚合物催化剂可以巧妙地进行定制,以确保在各种油源中提高生物柴油的产量,突出了其在生物燃料领域无与伦比的效率和多功能性。
