Eggshell based catalysts were synthesized by calcination (600 and 900 ºC, 4 h) of raw and rehydration (RH) modified (RH-temperature of 80 ºC, S/L ratio of 1/5, and RH-time of 6 h) eggshell. After RH-treatment, the sample underwent calcination at 600 ºC, 4 h. Obtained catalysts were characterized by XRD, SEM, N2-physisorption, and Hg-porosimetry, whereas the catalytic activity was analyzed in a batch reactor (reaction temperature of 60 ºC, sunflower oil/methanol molar ratio of 1/12, and catalyst concentration of 4 wt.%). The concentration of fatty acid methyl esters (FAMEs) was determined by HPLC. The reaction has reached equilibrium (FAME > 97%) with rehydrated catalyst for 1.5 h, whereas with catalyst calcined at 900 ºC for 4 h.
