چکیده
|
In this study, an attempt was made to optimize the conditions for the transesterification of sunflower oil with methanol, catalyzed by ca-k/al2o3 nanocatalysts, using response surface methodology. the examined variables were reaction temperature (55, 65 and 75 °c), reaction time (1, 2, 3, 4 and 5 h), catalyst weight base oil (3, 6, 9 and 12 wt%), ca content (20, 30, 50, 60 and 80 wt%), k content (5, 10, 15 and 20), methanol:sunflower oil molar ratio (3:1, 6:1, 9:1 and 12:1), calcination temperature (600, 700 and 800 °c) and calcination time (1, 2, 3 and 4 h). catalyst characterization was done by x-ray diffraction (xrd), scanning electron microscopy (sem), fourier transform-infrared spectroscopy (ftir) and temperature programmed desorption (tpd). the maximum fatty acid methyl esters (fame) conversion efficiency (biodiesel production efficiency) was 98.3%, at a calcination temperature of 800 °c for 3 h, a methanol-to-oil ratio of 9:1, a reaction temperature of 75 °c, a reaction time of 3 h and a catalyst-to-oil mass ratio of 9%.
