This work reports a kinetic study of catalyzed esterification of lauric acid with anhydrous ethanol related to biodiesel production. The catalyst consists of a clay mineral (montmorillonite STx1-b) prepared according to procedure previously described in literature. The acid activation was confirmed by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). Operating parameters:...
Direct esterification of waste oil materials (high FFA contents) and glycerol can be an important way to improve the energy goals and afford alternative sources to emulsifier production for food and cosmetics industry. This work reports an experimental study of free-solvent esterification of lauric acid with glycerol using a LDH (layered double hydroxide, Mg–Al–CO 3 ) as catalyst. The experiments...
This work report experimental kinetic data of ethyl esters production from auto-thermal esterification of lauric acid with ethanol and also using zinc laurates (ZnL 2 ) as catalyst. The experiments were performed in a mechanically stirred reactor evaluating the effect of temperature (120–250°C), ethanol to lauric acid molar ratio (MR) (3:1–9:1) and catalyst amount (2–10wt%). Chemical equilibrium...
