This present reported work was conducted to extract oil from Jatropha curcas seed, followed with the production of biodiesel via transesterification of resultant oil. The effects of methanol-to-oil ratio 1:1, 2:1, 3:1, 4:1, 5:1 and 6:1, reaction time of 30, 60, 90, 120 and 180min, at constant operating temperature of 60 o C were investigated. Also the energy input required for production of a unit biodiesel was calculated. The results of the study shows maximum biodiesel yield of 86wt% at methanol-to-oil ratio of 6:1, at reaction time of 180min. An energy input of ~1.4MJ/kg was estimated to produce a unit biodiesel from Jatropha curcas. The data reported in this study would improve fundamental knowledge in biodiesel production from Jatropha curcas seed as a renewable energy to complement fossil fuel.

“…These feedstocks include soybean oil [4], moringa oil [5], sunflower oil [6], rapeseed oil [7], palm oil [8], jatropha oil [9], camelina oil [10], neem oil [11,12], karanja oil [13], and sesame oil [14]. The ideal vegetable oil for biodiesel must be readily available, its plant should be easy to cultivate, and its composition must include a high percentage of monounsaturated fatty acids (C16:1, C18:1), a low proportion of polyunsaturated acids (C18:2, C18:3) and a controlled amount of saturated fatty acids (C16:0, C18:0) [15].…”

Statistical approach was employed to optimize biodiesel production from sesame oil in this work. Precisely, response surface methodology was applied, and the effects of four variables, viz. reaction temperature, catalyst amount, reaction time, and methanol/oil molar ratio, and their reciprocal interactions were determined. Central composite rotatable design was used to generate a total of 30 individual experiments, which were designed to study the effects of these variables during alkali-catalyzed methanolysis of sesame oil. A statistical model predicted the highest conversion yield of sesame biodiesel to be 99.71% at the following optimized variable conditions: reaction temperature of 63°C, catalyst amount of 1.04 wt.%, and methanol/oil molar ratio of 6.24, with a reaction time of 51.09 min. Using these variables under experimental condition in four independent replicates, an actual biodiesel yield of 98.36% was accomplished. The fuel properties of biodiesel produced were found to be within the ASTM D6751 and DIN EN 14214 biodiesel specifications.

“…As suas vantagens sobre o diesel de petróleo não podem ser subestimadas: é um combustível seguro, renovável, não--tóxico e biodegradável; que não contém enxofre; e possui uma maior ação lubrificante. Além disso, seu uso gera numerosos benefícios sociais como a revitalização rural, criação de novos postos de trabalho e redução do aquecimento global (KISS, DIMIAN & ROTHENBERG, 2008 Esses materiais à base de ácidos graxos podem incluir diversos tipos de sementes como a soja, pinhão manso, dendê, conforme mostrado na Figura 1, além do uso de sebo, banha e óleo residuais (ARANSIOLA et al, 2010). Os óleos vegetais mais comuns, cuja matéria--prima é abundante no Brasil, são soja, milho, algodão, babaçu e palma (PENILDO, 1981).…”

RESUMOO biodiesel apresenta muitas vantagens em comparação ao diesel por ser de origem renovável, biodegradável, podendo ser empregado de forma ambientalmente sustentável. A sua produção é comumente realizada através da reação de transesterificação por catálise homogênea. Entretanto, os catalisadores heterogêneos têm sido amplamente estudados por serem eficientes e passíveis de reciclagem, além de facilitar a purificação do biodiesel e minimizar a geração de efluentes. Neste trabalho, o óxido de cálcio (CaO) foi escolhido como catalisador básico para a reação de transesterificação por apresentar maior atividade, condições suaves de reação, menor custo e baixa toxidade, quando comparado com outros catalisadores comerciais. Foram avaliados os efeitos do tempo de reação no rendimento do biodiesel produzido com óleo de soja via rota metílica num processo em batelada, fixando a razão molar metanol/óleo em 12:1, temperatura em 65°C e concentração de catalisador em 8% em peso do óleo e variando o tempo do processo em 1h, 1,5h e 2h. Verificou--se que os efeitos relativos à variação do tempo de reação utilizada na síntese de biodiesel influenciam diretamente no processo. PALAVRAS--CHAVE:Biodiesel, Transesterificação, Catalisador Heterogêneo. INFLUENCE OF REACTION TIME IN BIODIESEL PRODUCTION VIA HETEROGENEOUS CATALYSIS ABSTRACTBiodiesel has several advantages compared to diesel, since it is produced from renewable sources, it is biodegradable and can be used in an environmentally sustainable way. Its production is commonly carried out through transesterification by homogeneous catalysis. However, heterogeneous catalysts have been widely studied due to its efficiency and for being suitable for reuse. In addition, heterogeneous catalysts could facilitate the purification of biodiesel and also to minimize the generation of waste. In this work, calcium oxide (CaO) was chosen as a basic catalyst for transesterification reaction because it presents high activity, mild reaction conditions and lower cost and toxicity, compared to other commercial catalysts. The effect of reaction time in the biodiesel yield has been investigated for biodiesel produced from soybean oil via methyl route in a batch reactor. In this process, methanol/soybean oil molar ratio was set at 12, reaction temperature 65 °C, catalyst/oil mass ratio 8% and reaction time of 1 h, 1.5 h and 2 h. It was found that the reaction time has a great influence on the process.
