Abstract

Bio-oil is a renewable energy source and has many compounds of industrial interest, but it also has undesirable characteristics such as high viscosity, corrosivity and high oxygen content, so separation means are necessary according to its application. There are many methods for the separation of bio-oil, so this review addresses the most used extraction techniques, among them: liquid-liquid, distillation, supercritical fluid extraction, catalytic cracking and adsorption. In addition, pyrolysis oils have promising characteristics for several applications, such as biodiesel production and also, due to their fungicidal effect, have been studied as pesticides applied in agriculture, which can positively impact food production, due to the reduction of water losses. food crops. The promising conditions and results reported in recent studies were presented, as well as possibilities for the application of bio-oil, with emphasis on the production of biodiesel and the possibility of using bio-oil as a fungicide agent. further studies on this topic, in order to contribute to scientific and technological development.
