“…Biofuels have increased in popularity because of rising oil prices and the need for energy security (Shirazi et al, 2013a). Among the various developed bioenergy sources such as bioethanol, biobuthanol or, biogas, biodiesel has attracted great interest due to its various advantages (Hasheminejad et al, 2011).…”

“…It is worth noting that one of the most challenging problems in the way of economizing biodiesel production is finding an available and low-cost source (i.e. vegetable oil for biodiesel manufacturing via transestrification, which is the most common method for methylesterification) (Hasheminejad et al, 2011;Chisti, 2013). In other words, using agricultural crops or algae is not economical yet, due to the rising global demand for water (Shirazi et al, 2012a).…”

HIGHLIGHTS EOM as a low-cost and emerging source for biodiesel production.  Improving coalescing filtration using electrospun nanofibrous for oil recovery.  Thermal treating of filters improve the coalescing efficiency. Biofuels have increased in popularity because of rising oil prices and the need for energy security. However, finding new raw sources for biodiesel production is still challenging. The oil which comes from wastewater effluent generated in edible oil mills (EOM) can be considered a low-cost, widely available, emerging and interesting source for biodiesel production. This study tries to improve the coalescing filtration by using electrospun nanofibrous filters for oil recovery from the EOM effluent. In order to improve the separation efficiency of the filters, thermal treatments (90 o C to 150 o C) were used. Results indicate that oil recovery using coalescing filtration is a promising method for providing a new source for making biodiesel production more economical.

“…La glicerina cruda, con una concentración máxima del 60% de glicerina, es de poco valor, ya que contiene gran cantidad de jabones, catalizador alcalino y metanol, y es medioambientalmente peligrosa, debido a este último compuesto; por tanto, para poder aprovecharla, debe llevarse al menos a un grado técnico (85% p/p de pureza), según Hasheminejad y colaboradores [5].…”

Como resultado del creciente mercado del biodiesel, se ha producido un aumento inevitable en la oferta de glicerina obtenida como subproducto del proceso. Con un abundante suministro barato de la glicerina sin refinar en el mercado, los investigadores buscan encontrar nuevas alternativas de uso. Por ello, en esta investigación se pretende analizar cómo la glicerina proveniente de la producción de biodiesel de aceite de palma puede ser la materia prima para la producción de químicos con un alto valor comercial por medios fermentativos y ser base para futuras biorrefinerías. A partir de la mezcla de glicerina, con diferentes sustratos por medio de un proceso de fermentación microbiana anaeróbica a partir de una cepa de Saccharomyces cerevisiae y una separación posterior, se pueden obtener diferentes productos de alto valor agregado como el etanol. Palabras clave: etanol, fermentación microbiana, glicerina, subproducto de biodiesel.Producing Ethanol from Glycerin, a Biofuel by-Product, Using Saccharomyces Cerevisiae abstract. The growing biofuel market has led to an inevitable increase in the availability of glycerin, a by-product of the production process. Due to this abundant supply of cheap unrefined glycerin, researchers are looking for new alternative uses. This research analyzes how the glycerin that comes from the production of palm oil biofuel could be used as the raw material for producing chemicals with high commercial value through fermenting agents, thus providing the basis for future bio-refineries. By mixing glycerin with different substrates via an anaerobic microbial fermentation process using a strain of Saccharomyces cerevisiae and prior separation, different products with high added value, such as ethanol, can be obtained.

RESUMOO biodiesel é um biocombustível importante para a matriz energética nacional é produzido de diferentes fontes oleaginosas, desempenhando papel importante na produção final do biocombustível. Diante de sua cadeia produtiva e da importância de métodos mais sustentáveis, realizou-se um estudo prospectivo sobre o processo simultâneo de produção de biodiesel visando à condensação das etapas de produção via simultaneidade de extração e respectiva conversão a partir de resíduos agroindustriais oleaginosos. Além disso, tem-se como objeto de estudo a utilização de catálise heterogênea ao sistema, agregando facilidades na separação do produto e do meio catalítico. Neste nicho de pesquisa e desenvolvimento de métodos alternativos para o setor do biodiesel encontram-se poucas patentes e artigos, sendo em sua maioria evidenciados processos em escala laboratorial. Sendo assim, tal tecnologia merece atenção, investimento e desenvolvimento para seu escalonamento, tendo em vista agregar diversos benefícios ao setor, desde a matéria-prima até o processo e distribuição.Palavras-chave: Biodiesel.

PROSPECTIVE STUDY ON THE PROCESS OF EXTRACTION OF AGRICULTURAL WASTE GRAIN MATERIAL WITH SIMULTANEOUS BIODIESEL PRODUCTION ABSTRACTBiodiesel is an important biofuel for the national energy matrix is produced from different oil sources, playing an important role in the final production of biofuel. In view of its production chain and the importance of more sustainable methods, a prospective study was carried out on the simultaneous production process of biodiesel, aiming at the condensation of the production stages through the simultaneity of extraction and respective conversion from agro-industrial oleaginous residues. In addition, the object of study is the use of heterogeneous catalysis to the system, adding facilities in the separation of the product and the catalytic medium. In this niche of research and development of alternative methods for the biodiesel sector are few patents and articles, being mostly evidenced processes in laboratory scale. Therefore, such technology deserves attention, investment and development for its scheduling, aiming to add several benefits to the sector, from the raw material to the process and distribution.
