“…Alkali‐catalyzed transesterification of triglycerides (TG) with alcohol can be adversely influenced by the FFA and water contents of the reaction mixture. High FFA and water contents, > 0.5 wt % and > 0.06 wt %, respectively, will cause soap formation, which could consume the catalyst and reduce its efficiency 31, 32. In the first step of the extraction process, methanol was used to remove the FFA and water in the cottonseeds.…”

Combined Production of Biodiesel and Nontoxic Cottonseed Meal Using Two‐Step Two‐Phase Solvent Extraction

The preparation of biodiesel and nontoxic cottonseed meal from cottonseed by two‐step two‐phase solvent extraction (TS‐TSE) combined with the transesterification reaction was investigated. The TS‐TSE process could significantly reduce the biodiesel production costs when compared with the two‐phase solvent extraction (TSE) process due to the reduction in methanol. A series of experiments was conducted to evaluate the effects of some factors on the fatty acid methyl ester (FAME) yield and free gossypol (FG) content. These conditions resulted in a maximum FAME yield and reduced the FG content in the cottonseed meal far below the Food and Drug Administration standard. The nontoxic cottonseed meal could be used as animal feed protein source.

“…Além disso, esse biocombustível possui propriedades semelhantes às do óleo diesel produzido a partir de petróleo e pode ser usado diretamente nos motores a diesel atuais ou usado como uma mistura com óleo diesel bruto (Wassell Jr. e Dittmer, 2006;Vicente, et al, 2007, Helwani et al, 2009. Por esta razão, o biodiesel tem recentemente atraído atenção, em diversos países, devido à sua disponibilidade, renovabilidade, não-toxicidade, melhor qualidade das emissões e sua biodegradabilidade (Chen et al, 2009;Demirbas, 2009;Wei Li et al, 2009;Hayyan et al, 2010;Liu et al, 2010;Patil et al, 2010).…”

“…Sabe-se que grande parte do custo total de produção de biodiesel equivale ao custo do óleo vegetal (70-95%), de acordo com Zhang et al, 2003;. Haas et al, 2006;Phan, 2008;Glisic et al, 2009;Sakai et al, 2009;Wen et al, 2010;Liu et al, 2010;Kiss et al, 2010. Sabe-se ainda que o alto custo do óleo vegetal é o principal fator econômico que faz com que o custo do biodiesel não seja competitivo (Predojevic, 2008;Liu et al, 2010).…”

Sabe-se ainda que o alto custo do óleo vegetal é o principal fator econômico que faz com que o custo do biodiesel não seja competitivo (Predojevic, 2008;Liu et al, 2010). É estimado que o biodiesel produzido a partir do óleo virgem seja de 10% a 50% mais caro que o óleo diesel de petróleo (IEA, 2008;Banerjee e Chakraborty, 2009;Han et al, 2009).…”

Palavras-Chave: óleo residual de fritura, cooperativas, biodiesel, viabilidade econômica de cooperativas.Key words: residual frying oil, cooperatives, biodiesel, economic viability of cooperatives. Recommended Citation Federal University of Rio de Janeiro -Brazil AbstractThe residual oil frying (ROF) is the cheapest raw material for biodiesel production. The collection and grouping of ROF is a popular practice of cooperatives, that's supply biodiesel plants. However, for the survival and performance of these cooperatives, these should generate profit. Therefore, this article represents a contribution by structuring and presentation a procedure of four stages, consisting in assist popular cooperatives in the analysis of generating profit by the ROF's collection and operation. This procedure was applied in an association of cooperatives located in the metropolitan region of Rio de Janeiro. From this application, it was concluded that the collection should planned by a software routing and her cost would have a reduction of almost 34% over the actual cost applied and the association of cooperatives would be able to generate profits and will be protected against market fluctuations, even if the price of ROF reached its lowest market price.

(2014) Análise de viabilidade econômica da participação de cooperativas populares na cadeia de fornecimento de óleo residual de fritura a fábricas de biodiesel. Journal of Transport Literature, vol. 8, n. 4, Ricardo César da Silva Guabiroba, Márcio de Almeida D'Agosto, Luíza Santana Franca* Resumo O óleo residual de fritura (ORF) é a matéria-prima mais barata para a produção de biodiesel. É uma prática de cooperativas populares a coleta e o agrupamento do ORF de modo a gerar escala de fornecimento a fábricas de biodiesel. No entanto, para a sobrevivência e atuação dessas cooperativas, estas devem gerar lucro. Assim sendo, este artigo tem como contribuição a estruturação e a apresentação de um procedimento composto por quatro etapas, voltado a auxiliar cooperativas populares quanto à análise de geração de lucro referente à operação de coleta do ORF. Esse procedimento foi aplicado à realidade de uma associação de cooperativas localizada na região metropolitana do Rio de Janeiro. A partir dessa aplicação, verificou-se que se a coleta fosse realizada de modo planejado a partir de um software de roteirização, o seu custo teria uma redução de quase 34% em relação ao custo real praticado e a associação de cooperativas estaria apta a gerar lucro, mesmo se o preço do ORF atingisse seu menor preço de mercado, estando protegida contra variações de preço estabelecidas pelo mercado.www.journal-of-transport-literature.org JTL|RELIT

“…Convection heating is based on superficial heat transfer, while dielectric heating transforms electromagnetic energy into heat in a volumetric and fast way. At the same time, the electromagnetic field could generate non-thermal effects, which can also accelerate destruction of lignocellulosic biomass crystallinity structure [15,16]. Depending on the wavelength, dielectric heating can be divided into two categories, namely microwave and radio frequency (RF) heating.…”
