• Abstract:

  Residual frying oil is a very abundant waste, which makes it easy and favorable to obtain and desire for industrial reuse. Taking into consideration, the large consumption of oils and diverse uses, a fact that generates inadequate disposal, causing environmental harm. The disposal of waste is generally done improperly and, recognizing these harms, interest is aroused in reuse and safe disposal with the aim of adding value and sustainable functionality.
  Aiming at these characteristics, the work aimed to synthesize bio-oil through the reuse of residual frying oil with the use of red mud (LV) as a catalyst (5%, 10%, 15% and 20% m/m) in order to obtaining an increase in yield as well as studying the temperature behavior of the process. This way, the linear behavior of the process temperature over time was observed and the use of LV proved to be effective in breaking down the triglyceride molecules, with a 20% m/mo greater yield of bio-oil (68.73 %).
