Abstract:

CaO, SrO and K3PO4 were employed as solid catalysts (5% w/woil) for biodiesel production via transesterification with methanol. The starting substrate was fried vegetable oil, in order to valorize this residue as biofuel. The effectiveness of the solid catalysts were compared with NaOH (homogeneous catalyst) in terms of FAME (fatty acid methyl ester) yield. Trials by re­using the recovered catalyst were performed in order to assess their catalytic deactivation. In the case of SrO and CaO, the solid catalyst was employed both as powder and granules, in order to verify the possibility of its utilization in packed bed reactors and reducing overpressure. Results show that, at the transesterification conditions of 3 h at 65 °C, the FAME yields were 97% for NaOH (homogeneous catalyst), 91% for CaO, 84% for SrO and 78% for K3PO4. In the case of CaO and SrO no significant differences were observed between the use of powder and granules.
