Abstract

This project seeks to improve the magnetic properties of ferrofluids to optimize the con converting electromagnetic energy into heat through the magnetohyperthermia (MH) effect, to application in the recovery and transport of oil or any viscous fluid, reducing its viscosity. MH is the phenomenon that allows the temperature increase in a system with magnetic nanoparticles (NPs) in the presence of an alternating magnetic field, when the electromagnetic energy from the magnetic field is transformed into heat by magnetization inversion of NPs. The viscosity of a liquid, on the other hand, decreases as the temperature increases. Liquids with high viscosity are present in several industries such as Oil & Gas, pharmaceutical, chemical and food, where viscosity reduction can betranslate into lower costs of extracting or transporting liquids. The possible implementationof magnetic nanoparticles in this technological problem has its origin in a fundamental associated with the dispersion of magnetic nanoparticles in viscous fluids. so with In this project we intend to develop new methods of synthesis of colloidal systems of nano-magnetic particles aiming their implementation of extraction or transport technologies of fluids.
