Sažetak
To reduce the impact on climate change, stricter regulations on the composition of diesel fuel have been enacted in recent decades to reduce emissions. This has reduced the amount of sulphur, aromatics, and olefins in the fuel, resulting in an increase in n-paraffin content. This improves combustion properties but has the disadvantage of worsening low-temperature properties. Our research is focused on synthesizing polymer additives that improve these properties, with an emphasis on additives that improve flowability. The synthesized additives are based on benzyl methacrylate (BMA) with octadecyl methacrylate (ODMA), dodecyl methacrylate (DDMA) and 2-(tert-butylamino)ethyl methacrylate (TBAEMA) with different molar ratios of the comonomers. The additives were synthesized by radical polymerization in toluene solution with a radical initiator at 96 °C. The thermal properties of the additive formulations with non-additivated diesel fuel were investigated by differential scanning calorimetry (DSC). The influence of the additive on the crystal morphology and crystallization behavior was studied by optical microscopy with polarization, and the pour point (PP) was investigated according to ASTM D5950. The results obtained with the synthesized additives showed a significant improvement in the low- temperature properties of diesel, with a decrease in the PP temperature by up to 27 °C.
