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

Mixing in flows past confined microfluidic cylinders: Effects of pin and fluid interface offsetting

“…A typical example is when dealing with different molar ratio and/or flow rate of reactants, as in biodiesel synthesis in microreactors [24,25]. In accordance with the standard ASTM D6751-15 [26], biodiesel is made up by mono-alkyl esters of longchain fatty acids fuel, derived from vegetable oils and/or animal fats, commonly produced via transesterification reaction.…”

Innovative Metallic Microfluidic Device for Intensified Biodiesel Production

“…3,7,10,13−17,25−32 The alcohols that are most frequently used in the transesterification process are methanol and ethanol because of their low cost, availability, and their physical and chemical properties. 33 Most of the studies that perform the synthesis of biodiesel through the transesterification reaction in micro reactors use methanol as the alcohol, 3,7,10,13,14,17,[24][25][26]28 while a few studies use ethanol. 27,29−31 Methanol, aside from being toxic, is usually produced from petrochemical materials, while ethanol is produced from biomass.…”

“…These reactors are composed of microchannels with transversal sections presenting different geometries and with hydraulic diameters smaller than 1 mm. These devices can achieve rapid reaction rates because of short diffusion distances and a high surface area/volume ratio, which improves (“intensifies”) heat and mass transfer. ,− …”

“…The alcohols that are most frequently used in the transesterification process are methanol and ethanol because of their low cost, availability, and their physical and chemical properties . Most of the studies that perform the synthesis of biodiesel through the transesterification reaction in micro reactors use methanol as the alcohol, ,,,,,,− , while a few studies use ethanol. ,− Methanol, aside from being toxic, is usually produced from petrochemical materials, while ethanol is produced from biomass . Thus, biodiesel produced from ethanol is completely derived from renewable sources. ,, In addition, Brazil is one of the largest ethanol producers in the world Because of these characteristics, ethanol was chosen to be used in the present study.…”
