Abstract
Two approaches for metal ion incorporation were employed to introduce Ca2+ into
SBA-15; Direct Synthesis (DS) and Wet Impregnation (WI). The non-ionic template was removed
by two different methods; calcination and solvent extraction. The obtained catalysts
were characterized by means of X-Ray Powder Diffraction (XRD), Energy Dispersive X-ray (EDX),
and FT-IR spectroscopy. The basicity was determined by using Hammett indicators and benzoic acid
titration. The effects of synthesis methods and organic template on basicity and catalytic
performance were studied in the transesterification of Canola oil with methanol. 1H NMR was used
to analyze the products. The best results were obtained using catalysts which prepared by
wet impregnation method. Furthermore calcination is a better method of template removal. So calcined
Ca/SBA-15 prepared by impregnation showed particularly the highest activity (conversion 84.2 %).
Although this catalyst has a limited reusability in transesterification reaction.
