“…They are the most commonly employed feedstock for biodiesel production and about 95% of biodiesel from the biofuel market comes from this source. The most commonly employed plant seed oils are soybeans, 17 palm oil, 101, 110 palm kernel oil, 59 rapeseed, 90 sunflower 111, 112 canola, 113 coconut, 68 peanut, 90 jatropha 25 and many others that have been commercially developed. These oils are produced in large quantities in many regions of the world and their fuel properties are similar to those of petroleum diesel and are very effective in emission mitigation 28 .…”

Biodiesel has the potential to contribute significantly to the elimination of the present global energy and climate change logjam, but its production and commercialization have been hindered by the diverse nature of the feedstocks used for production. This paper reviews the effectiveness of applying various types of crop and animal waste-derived catalysts together with innovative feedstock hybridization as an economically viable technique for biodiesel production. Feedstock challenges, availability, and sustainability for large-scale applications are addressed with a view to bridging the existing gaps. Challenges in the use of edible oils and algae oil sources and development remain, but the technique of feedstock hybridization appears to be very promising, innovative, and cost-effective for biodiesel production. The present state of biodiesel production could be improved by the application of simple and cost-effective technologies in the feedstock system. High free fatty acid (FFA) content is the major hurdle to the use of most oils, especially low-grade/advanced oil feedstocks, in biodiesel production. This could be addressed through technological application of feedstock hybrids and biogenic waste-derived heterogenous catalysts, and their biochemical modifications. Conventional technology for the large-scale application of inorganically derived catalysts in biodiesel production with various characteristic differences is presented. Heterogenous catalysts derived from biogenic wastes and their modification could be used to overcome associated problems with the use of inorganic catalysts in biodiesel production. Biogenic waste-derived heterogenous catalysts are renewable, available, eco-friendly, and cost-effective. Technological applications of heterogeneous catalysts derived from biogenic waste are outlined and reviewed, considering various materials and different modification techniques to identify appropriate options for scaling up development. This review also discusses fundamental considerations for the Review

HS SANTANA) RESUMO -Este trabalho tem como objetivo a construção de uma microplanta para produção de biodiesel utilizando técnicas de impressão 3D, bem como a obtenção de dados sobre escoamento, uniformidade de fluxo e rendimento da reação. Os testes de vazão na microplanta apontaram desvio de 4,2% na uniformidade de fluxo devido à queda de pressão na tubulação. Nos testes de reação em milirreator observou-se o efeito da temperatura, razão molar etanol/óleo e concentração de catalisador no rendimento da reação, sendo o máximo rendimento obtido de 73.51% em um tempo de residência de 10 s. O rendimento global da microplanta composta de 4 milirreatores foi de 42%, em que biodiesel foi produzido a uma taxa de 126,4 mL min -1 .

This paper investigates glycerol and glycerides extraction process from fresh and waste sunflower oil biodiesel.Deep eutectic solvent choline-chloride: ethylene-glycol (molar ratio 1:2.5) was used as extraction media in both batch experiments and continuous Karr column. Biodiesel was synthesized in an alkali catalysed chemical transesterification reaction. Three process variables, namely hydrodynamic conditions, solvent to biodiesel ratio and extraction duration were investigated and their impact on the extraction efficiency was found to be largely negligible. Throughout the whole range of process variables the extraction efficiency was relatively high, getting slightly lower only during the continuous experiments. After the extraction, free glycerol content was below the limit for all samples, but the total glycerol and glycerides content was too high to fully comply with biodiesel quality standards. Selected extraction solvent has proved to be efficient for free glycerol removal in the tested range of conditions, but further process modifications and possible raw material and biodiesel processing will be needed to reduce the content of total glycerol and glycerides.
