Abstract

Biodiesel, compatible with compression ignition engines, is a promising alternative to fossil fuels due to its renewable and environmentally friendly nature. However, the high cost of biodiesel production stems from inefficiencies in industrial processes. This review summarizes the recent developments in advanced biodiesel synthesis techniques, evaluating various catalysts, including homogeneous, heterogeneous, biocatalysts, nanocatalysts, and ionic liquids, alongside factors such as feedstock generations, lipid content, and operating conditions affecting biodiesel yield. Third-generation feedstocks, particularly algae, demonstrate superior energy and oil content and eco-friendly characteristics. Among the techniques, supercritical transesterification shows significant potential for enhanced production. Methanol-based transesterification remains the most cost-effective and efficient method for commercial biodiesel synthesis. The study also analyzes various uncertainty methods and emphasizes the importance of continued innovation, including genetic engineering, to advance biodiesel production and foster its adoption as a sustainable energy source for a cleaner future.

生物柴油生产技术的发展综述

生物柴油与压缩点火发动机兼容，具有可再生和环保的特点，是一种很有前途的化石燃料替代品。然而，生物柴油生产的高成本源于工业过程的低效率。本文综述了先进生物柴油合成技术的最新进展，评估了各种催化剂，包括均相催化剂、多相催化剂、生物催化剂、纳米催化剂和离子液体，以及影响生物柴油产量的因素，如原料世代、脂质含量和操作条件。第三代原料，特别是藻类，具有更高的能量和含油量以及环保特性。其中，超临界酯交换法具有显著的增产潜力。甲醇基酯交换反应仍然是最具成本效益和最有效的商业生物柴油合成方法。该研究还分析了各种不确定性方法，并强调了持续创新的重要性，包括基因工程，以促进生物柴油的生产，并促进其作为可持续能源的采用，以实现更清洁的未来。

期刊介绍： The journal Energy Conversion and Management provides a forum for publishing original contributions and comprehensive technical review articles of interdisciplinary and original research on all important energy topics. The topics considered include energy generation, utilization, conversion, storage, transmission, conservation, management and sustainability. These topics typically involve various types of energy such as mechanical, thermal, nuclear, chemical, electromagnetic, magnetic and electric. These energy types cover all known energy resources, including renewable resources (e.g., solar, bio, hydro, wind, geothermal and ocean energy), fossil fuels and nuclear resources.
