Microreactor Fabrication by Photolithography and Analysis for Synthesis of Biodiesel
نویسنده
چکیده
This work presents an analysis about microreactors of different geometries for the biodiesel synthesis. The microreactors were made by a polymeric substrate with the photolithography technique. Simulations were made using the computational fluid dynamics software ANSYS-CFX. They show the flow behavior through the microchannels. Experiments were performed to produce biodiesel, with syringe pumps injecting alcohol and oil with specified flow, to control the alcohol/oil molar ratio. Ethanol and soybean oil were used to produce biodiesel with sodium hydroxide as catalyst. For these experiments, Omega and Tesla shaped microreactors were produced. Samples were prepared to chemical analysis to discover the percentage of oil converted in biodiesel. It has been shown that is possible to produce biodiesel in microreactors resulting in 81% of conversion in this work.

In the present study, Choline hydroxide (ChOH) as an ionic liquid catalyst was used for transesterification of soybean oil into biodiesel in a microchannel reactor. The effects of three variables i.e. reaction temperature, catalyst dosage and total flow rate on fatty acid methyl ester (FAME) content (wt. %) were optimized using Box–Behnken experimental design. In order to predict the FAME conte...
