Glycerol phase is a liquid byproduct of biodiesel production. It contains mainly glycerol, methanol and fatty acids. All these materials can be further processed and used as input material in various applications (Glycerol - animal feed ingredient, in biogas plants, in chemical, food, pharmaceutical and construction industries. Methanol – the production of biofuels, chemical industry. Fatty acids - the production of biofuels, cosmetic industry, etc.).
In Biodizel Vukovar production process solution of sodium hydroxide in pure methanol is used as catalyst.
