“…(2) and in agreement with the results reported by Abdullah et al (2009). This can be easily justified as increase in reaction temperature leads to higher reaction rate; longer reaction duration was required to complete the conversion; higher molar ratio of methanol to oil was required in this reversible reaction to shift the equilibrium towards product formation; higher catalyst loading was required to increase the availability of active sites.…”

“…The fit quality of the models was judged from their correlation of determination (R 2 ) (Abdullah et al, 2009;Rashid et al, 2009). A given mathematical model was only considered acceptable when its analysis of variance reached high statistical significance (favorable adjustment values and no apparent lack of fit), with F values within a level of confidence of 95% and p values <0.05 (Domingos et al, 2008;Rashid et al, 2009).…”

Conversion of waste edible oil to the fatty acid methyl esters was optimized using sulfuric acid as a catalyst for transesterification and esterification simultaneously, and adding tetrahydrofuran as a cosolvent for producing a homogeneous media. The optimized model was established by the response surface methodology. The optimum conditions were methanol/oil molar ratio of 21:1, 3.95% of sulphuric acid based on the oil mass, and reaction period of 3.3 h at 64 ı C in the presence of tetrahydrofuran, obtaining a fatty acid methyl esters yield of 98.2%. Further verification experiments confirmed the validity of the predicted model. The result suggested that the present work had a significantly lower reaction temperature and methanol/oil molar ratio by the addition of tetrahydrofuran to the reaction system.

“…According to Pinzi et al (2010), RSM is a powerful tool that has many advantages, such as more information per experiment than unplanned approaches, a reduction in the number and cost of experiments and it makes the calculation of the interactions among experimental variables possible within the range studied, leading to better knowledge of the process. Although the application of RSM for biodiesel production is still used only occasionally (Vicente et al, 2007), some researchers have successfully applied it to optimize the alcoholysis reaction (Abdullah et al, 2009;Jeong et al, 2009;Rashid et al, 2011;Silva et al, 2011).…”

SUMMARY:This paper presents an acid pre-treatment process and a kinetic study for the esterification reaction of Oleum papaveris seminis oil with methanol in the presence of amberlite 120 as a solid catalyst to convert the oil into methyl esters. Response surface methodology (RSM) was applied to optimize the reaction parameters, i.e. reaction time, percentage of the catalyst and volume ratio of methanol to oil. The results revealed that 0.87% w/w of catalyst concentration and 44.70% v/v of methanol to oil ratio provided final free fatty acid (FFA) contents of 0.60% w/w at 102.40 min of reaction time. It proved that the contribution of Amberlite 120 in the esterification of FFA was highly significant. The kinetics of the esterification in Oleum papaveris seminis oil with methanol in the presence of the amberlite 120 catalyst were also investigated to establish the reaction rate constant (k), reaction order, and activation energy. The study was performed under the optimized parameters at three reaction temperatures (50, 55, and 60 °C). The value of k was in the range of 0.013 to 0.027 min Optimización y estudio cinético. En este artículo se presenta un proceso de pre-tratamiento con ácido, y un estudio cinético de la reacción de esterificación. Se utiliza Oleum papaveris seminis con metanol en presencia de Amberlite 120 como catalizador sólido para la formación de los ésteres metílicos. Se aplicó una metodología de superficie de respuesta (RSM) para optimizar los parámetros de la reacción; es decir, tiempo de reacción, porcentaje de la relación de catalizador y volumen de metanol -aceite. Los resultados mostraron que el 0,87% w/w de la concentración de catalizador y 44,70% v/v de metanol en relación al aceite dan lugar a un contenido final de ácidos grasos libres (FFA) de 0,60% w/w en 102,40 min de tiempo de reacción. Se demostró que la contribución de Amberlite 120 en la esterificación de los FFA fue altamente significativa. La cinética de la esterificación del Oleum papaveris Seminis con metanol en presencia del catalizador Amberlite 120 también se investigó para establecer la constante de velocidad de reacción (k), orden de la reacción, y la energía de activación. El estudio se realizó bajo los parámetros optimizados a tres temperaturas de reacción (50, 55, y 60 °C). El valor de la constante k fué del rango de 0.013 a 0,027 min −1 . El modelo de cinética de primer orden fue el adecuado para esta esterificación FFA irreversible con una energía de activación de aproximadamente 60,9 KJ mol −1 .
