ORTEGA-ALEGRIA, Daniel Rodrigo  e  FLOREZ-MARULANDA, Juan Fernando. Design and manufacturing of an ultrasonic reactor for biodiesel obtaining by transesterification. Dyna rev.fac.nac.minas [online]. 2019, vol.86, n.211, pp.75-83. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v86n211.78518.

It presents the design, development, and implementation of the ultrasonic reactor in laboratory level for batch transesterification with temperature variation, with a mechanic and electronic modular development; its operational characteristics were obtained through commercial equipment revision. To evaluate its performance, a mixture was made using castor oil, methanol, and potassium hydroxide, to obtain biodiesel and glycerin; by taking the glycerin stoichiometric value obtained in the reaction as the reference production value, an efficiency of 97% was reached with only the ultrasound incidence. In the processes with external temperature incidence, it was observed that it influences the reaction speed, since the stabilization times are around 30% less than the other observed processes.

Palavras-chave : ultrasound; transesterification; biodiesel; modular development; efficiency.
