“…Biodiesel production using solid base as catalysts is an effective and viable technology for transesterification of triglycerides, and the catalyst can be separated from liquid products and reused with or without regeneration [2][3][4]. Moreover, successful utilization of solid catalysts can decrease the cost of production and the environmental pollution, which is usually encountered in the homogeneous process [5][6][7].…”

Biodiesel is an alternative to petroleum-derived diesel fuel; development of a high-efficiency base catalyst to be used in heterogeneous biodiesel production is still a challenge. In this paper, a novel solid base catalyst, KF-and CaOsupported montmorillonite (KCa/MMT) was successfully synthesized by a facile impregnation method, and used for producing biodiesel in transesterification of commercial soybean oil with methanol. The catalysts were characterized by X-ray diffraction, carbon dioxide temperature-programmed desorption and scanning electron microscopy. Effects of the parameters, such as the loading amount of KF, the amount of KCa/MMT, and the methanol to oil molar ratios, on the yield of biodiesel were investigated. A maximum biodiesel yield of 98 % was obtained under the optimal reaction conditions. The separated catalyst can be directly used in the next round of reactions and gave a satisfactory yield. Furthermore, analysis of the catalyst's tolerance to oil-containing water or free fatty acids, and a kinetic study were also carried out. Koros-Nowak tests were designed and conducted, and it was proven that the heat and mass transfer were not limited by the reaction rate.

“…The primary biofuels are used in an unprocessed form, primarily for heating, cooking, or electricity production, such as fuel wood, wood chips, and pellets, etc. The secondary biofuels are produced by processing of biomass, e.g., ethanol, biodiesel, dimethyl ester (DME), etc., that can be used in vehicles and various industrial processes (Table 4.9 ; Savaliya et al 2013 ). The secondary biofuels are further divided into fi rst, second, and third generation biofuels on the basis of the raw material and technology used for their production.…”

“…Biofuels are also classifi ed according to their source and type. Secondary fuels are modifi ed primary fuels, which have been processed and produced in the form of solids (e.g., charcoal), or liquids (e.g., ethanol, biodiesel, and bio-oil), or gases (e.g., biogas, synthesis gas, and hydrogen), as reviewed by Savaliya et al ( 2013 ).…”

“…A primeira geração mais conhecida de biocombustíveis é o etanol, que é extraído pela fermentação do açúcar de plantas cultivadas e amido contido em grãos de milho (AMORIM et al, 2011;CANAKCI;SANLI, 2008;MOSER;VAUGHN, 2012;SOUZA et al, 2014), e o biodiesel produzido a partir de plantas oleaginosas como a mamona e grãos de soja (DANTAS et al, 2011;ESCOBAR et al, 2009;SAVALIYA;DHORAJIYA;DHOLAKIYA, 2013).…”

“…Os biocombustíveis de segunda geração são produzidos pelo processamento da biomassa celulósica de plantas (SAVALIYA; DHORAJIYA; DHOLAKIYA, 2013;SOCCOL, 2009). Para a obtenção de biocombustíveis de primeira e segunda geração, há a necessidade de áreas agricultáveis para a obtenção da matéria prima, o que é um inconveniente, já que competem com a produção de alimento (GISELRØD;PATIL, 2008).…”

Produção de Bioetanol Utilizando Microalgas: Uma Revisão

et al. 2016

ResumoA busca por biocombustíveis foi impulsionada nas ultimas décadas devido à preocupação com o esgotamento das fontes enérgicas não renováveis. Essa revisão de literatura oferece uma abordagem da aplicação de microrganismos para a produção de bioetanol, com ênfase para as microalgas. A elevada eficiência de conversão fotossintética, o rápido crescimento, a possibilidade de manipulação do meio de cultivo a fim de produzir biomassa com elevado teor de lípidos e carboidratos, e o uso de áreas com baixa aptidão agrícola fazem das microalgas uma das matérias primas mais promissoras para a produção de biocombustíveis. A existência de uma grande variedade de métodos para a obtenção de biomassa microalgal e posterior produção de bioetanol, estimulou diversos estudos para aumentar o potencial de produção e aperfeiçoar o processo. Estudos apontam que para a produção de bioetanol atingir viabilidade econômica, a produção da biomassa algal deve objetivar ainda a obtenção de outros compostos, de maior valor agregado, como pigmentos, proteínas, ácidos graxos poli-insaturados, obedecendo ao conceito das biorrefinarias integradas. The search for biofuels has been driven in recent decades due to concern over the depletion of nonrenewable energetic sources. This literature review provides an approach to the application of microorganisms for the production of bioethanol, with emphasis on microalgae. The high efficiency of photosynthetic conversion, rapid growth, the possibility of manipulation of the medium to produce biomass with high fat and carbohydrates, and the use of areas with low agricultural potential of microalgae are one of the most promising raw materials for the production of biofuels. The existence of a large variety of methods for obtaining microalgal and subsequent production of bioethanol, biomass stimulated numerous studies to increase the production potential and improve the process. Studies show that for the production of bioethanol achieve economic viability, production of algal biomass should also aim at obtaining other compounds with higher added value, such as pigments, proteins, polyunsaturated fatty acids, according to the concept of integrated biorefineries.
