Sažetak
This paper studied the influence of four reaction parametersetemperature (40-80 °C), time (1-3 h), mass % of catalyst (1-3 wt%) and molar ratio of 1- propanol to sunflower oil (6:1e10:1)eon the conversion of biodiesel. To achieve a conversion of 95% or above, the transesterification was optimized to reduce the time, temperature, molar ratio of 1-propanol to sunflower oil and mass % of catalyst. The optimal conditions were a temperature of 40 °C, time of 1 h, 1-propanol to oil molar ratio at 8.71:1 and mass % of catalyst of 1.96%. The fatty acid propyl esters (FAPRE) were purified and blended with 1-propanol and mineral diesel to determine the application properties as transportation fuels. The addition of FAPRE to diesel increases the density and viscosity and improves the lubricity with no effect on CFPP even with 10 vol% of FAPRE. On the contrary, the addition of 1-propanol in the FAPRE- diesel blends had an opposite effect (decrease in density, viscosity and lubricity). Nevertheless, all the blends satisfied the requirements according to EN 590 for the tested properties.
