Biodiesel synthesis processes including pyrolysis, direct blending, transesterification, and advanced technologies such as microwave- and ultrasound-assisted and supercritical processes from palm oil mill effluent (POME) are reviewed to highlight the significance and advances in terms of process sustainability and cost. POME as the most contaminated waste can be effectively utilized for biodiesel production. Supercritical transesterification offers more advantages over the other processes including higher reaction rate, without catalyst constraint, producing pure glycerol, and simple product separation process. The addition of co-solvents like CO2 should be investigated for supercritical biodiesel production from POME. Although POME is an inexpensive source to synthesize biodiesel, innovative processes are needed to maximize the oil recovery from POME. Optimization of transesterification parameters is required for high production yields and sustainable processing.

棕榈油厂废水生产生物柴油的综合评价

回顾了生物柴油合成工艺,包括热解、直接混合、酯交换和先进技术,如来自棕榈油厂流出物 (POME) 的微波和超声波辅助和超临界工艺,以突出其在工艺可持续性和成本方面的重要性和进步。POME 作为污染最严重的废物可以有效地用于生物柴油生产。超临界酯交换与其他工艺相比具有更多优势,包括更高的反应速率、无催化剂约束、生产纯甘油和简单的产品分离过程。添加 CO 2等助溶剂应研究从 POME 生产超临界生物柴油。尽管 POME 是合成生物柴油的廉价来源,但仍需要创新工艺以最大限度地提高 POME 的石油回收率。需要优化酯交换参数以实现高产量和可持续加工。
