Gliceryna – produkt uboczny procesu wytwarzania biodiesla
Glycerol as a By-product of Biodiesel Production

Summary/Abstract: The paper presents the physical and chemical properties of glycerol and how it is used. It also shows methods of the industrial processing of glycerine fraction – in terms of obtaining and concentrating it – and methods of biodiesel production, of which glycerine is a by-product. The paper evaluates the possibility of concentrating glycerol by removing other compounds of technical glycerine using carbon adsorbents (ARP2) prepared with oxygen active centers. The most important aspect of this approach is to eliminate the energy consuming rectification process. Results of this study show that concentrating glycerol using specially selected carbon sorbents is a valid process.
