Abstract

The magnesium hydroxide fluorides, MgF_x(OH)_2-xwith different aging temperatures have been synthesized by the sol-gel method. The resulting materials were characterized by various techniques such as XRD, FT-IR, TG/DTG, N₂adsorption-desorption, pyridine FT-IR and SEM, respectively. The catalytic evaluation of samples was investigated in the simultaneous transesterification and esterification between waste cooking oil (WCO) containing different %FFA and methanol to yield biodiesel. The performance of the catalyst, especially MgF_x(OH)_2-xaged at room temperature (RT) showed higher biodiesel yield compared to MgF_x(OH)_2-xwith increasing of aging temperature. The higher catalytic activity could be attributed to Brønsted acid site, pore diameter size and volume of the materials. Moreover, the yield of biodiesel was not correlated with the surface area of MgF_x(OH)_2-x.The reusability or lifetime of catalyst decreased after three runs used.
