Examination of Selected Physicochemical Properties of Biodiesel after Electron Beam Sterilization in Flow System

The problem of microbial growth in fuels, especially biofuels, is a very important issue. Water necessity for to occur. Unfortunately, it hard exclude all water from fuel systems during daily operations, when biodiesel added the mix. aim this work was investigate impact ionizing radiation on selected properties fatty acids methyl esters order evaluate possibility using irradiation techniques sterilize and its blends. Ionizing influences chemical composition samples containing unsaturated bonds. Irradiation performed specially designed flow system. tested parameters were compared with normative values ISO 14214 standard. Density, kinematic viscosity, flash point, content cold filter plugging point as macroscopic do not change despite their radiation. Change observed microscopic oxidation stability content. During irradiation, Rapeseed Methyl Ester (RME) formed products, which lower oxidative stability. It that, content, requirements standard could be met case small doses. In RME saturated water, changes ester concentration smaller, but resulting products decreased Sterilization (FAME) use e beam apply low doses (up 2 kGy) system without adding water. FAME by requires higher radiation, adversely affects
