Continuous biodiesel production waste cooking

项目摘要

Global environmental efforts to decarbonise the power and transport sectors has led to significant investment and research into alternative fuel sources. Biodiesel could be an alternative to fossil fuels as a source of low carbon energy, however, its implication on food security urges consideration of non-edible based feedstocks and biomass wastes. For instance, used cooking oil (UCO) is one such alternative, offering a beneficial circular economy for biodiesel production as a cheap source of feedstock and with no implications on food security. For efficient and economical conversion of UCO to biofuel, suitable catalysts must be developed with high selectivity towards biodiesel production and resistance to feedstock impurities, such as Free Fatty Acids (FFAs). Such catalysts must either be continually regeneratable or remain active throughout extended operation, as well as being easily separated from the effluent biodiesel stream. The novel catalyst is a core-shell functionalised magnetic nanoparticle that will be synthesised and characterised as part of this work. UCO with varying levels of impurities (e.g. different levels of FFAs) will be used as a cheap feedstock. The catalyst selectivity and stability will be studied initially in batch operation, however ultimately as part of a continuous reaction system. The potential to continually remove catalyst via external magnetic field and apply radiofrequency heating for temperature control will also be explored. Finally, the effect of the catalyst performance on the properties of the produced biodiesel will be investigated to overall determine the suitability of such nanocatalysts in a full-scale industrial setting.

全球为电力和运输部门脱碳所做的环保努力，导致了对替代燃料来源的大量投资和研究。生物燃料可作为化石燃料的一种替代品，作为低碳能源，但其对粮食安全的影响促使人们考虑使用非食用原料和生物质废物。例如，用过的食用油就是这样一种替代品，它为生物柴油生产提供了一种有益的循环经济，作为一种廉价的原料来源，而且对粮食安全没有影响。为了将UCO有效且经济地转化为生物燃料，必须开发对生物柴油生产具有高选择性和对原料杂质如游离脂肪酸（FFA）具有抗性的合适催化剂。这种催化剂必须是可连续再生的或在整个延长的操作中保持活性，以及容易从流出的生物柴油流中分离。这种新型催化剂是一种核壳功能化的磁性纳米颗粒，将作为这项工作的一部分进行合成和表征。具有不同水平杂质（例如不同水平的FFA）的UCO将被用作廉价原料。催化剂的选择性和稳定性最初将在间歇操作中进行研究，但最终将作为连续反应系统的一部分。还将探索通过外部磁场连续去除催化剂和应用射频加热进行温度控制的潜力。最后，将研究催化剂性能对所生产的生物柴油的性质的影响，以全面确定这种纳米催化剂在全规模工业环境中的适用性。
