Inverse determination of kinetic rate constants for transesterification of vegetable oils

Estimation of kinetic coefficients in micro-reactors for biodiesel synthesis: Bayesian inference with reduced mass transfer model

“…The development of alternative sources of fuel, such as biodiesel, has been progressively motivated by growing concerns about the decline in petroleum reserves, the cost of petroleum, and the increase in environmental problems generated mainly by pollution from fossil fuel combustion (Dennis et al, 2008;Sun et al, 2010;Leung et al, 2010).…”

“…Biodiesel is an alternative fuel and has as its main characteristics to be environmentally friendlier than diesel produced from petroleum, biodegradable and non-toxic (Meher et al, 2006;Dennis et al, 2008 (Demirbas, 2008;Wen et al, 2009;Charoenwat and Dennis, 2009). Due to the high residence times, many studies have been developed with the purpose of reducing this reaction time to improve the efficiency of biodiesel production (Pengmei et al, 2010;Falahati and Tremblay, 2012;Rahimi et al, 2014).…”

“…The estimation of the kinetic coefficients requires the solution of the associated inverse problem for mass transfer within the microscale. Some studies on parameter estimation were carried out using optimization of an objective function (Al-Dhubabian, 2005;Dennis et al, 2008;Richard et al, 2013;. However, very few works in the literature addressed the estimation of kinetic coefficients involved in the biodiesel transesterification reaction within the micro-reactor framework (Al-Dhubabian, 2005;Dennis et al, 2008;Richard et al, 2013;Schwarz et al, 2013;Naveira-Cotta, 2016, Santana et al, 2016;Santana et al, 2017).…”

In addition, there are several possible combinations in terms of vegetable oil and catalyst that remain untouched in the available literature.…”

Innovative Metallic Microfluidic Device for Intensified Biodiesel Production

“…[1][2][3][4] Biodiesel is an alternative to the petrochemically sourced diesel because they are typically biodegradable, non-toxic and presents low carbon and sulfur content and when burned emits less particulate and unburned hydrocarbon emissions. 1,5,6 In addition, biodiesel is considered a source of renewable energy that can totally or partially replace diesel produced from petroleum because biodiesel has energetic properties similar to diesel. 6 Biodiesel is commonly produced commercially by the transesterification reaction of a vegetable oil, frying oil or animal fat with short chain alcohols such as methanol or ethanol, using catalysts that can be basic, acidic or enzymatic.…”
