摘要：
Fatty acid methyl esters (FAME) are used as alternative diesel fuel made from renewable sources. The attention is oriented to the materials that do not compete with food and feed production. Significant potential as an alternative low-cost biodiesel feedstock present used frying oils (UFO). The chemical changes of triacylglycerols which take place during frying can be so extensive that the properties of the FAME made from UFO (UFOME) should not meet all requirements of the standard EN 14 214. The key problem is FAME oligomers which lower the ester content and increase the viscosity. In this work, the results of oligomer content determination using gel permeation chromatography (GPC) and gas-liquid chromatography (GLC) are presented. Effective method for oligomer removal from UFOME is their final treatment based on UFOME distillation in vacuum film evaporator.
