In this study, MgO–Li2O catalysts were developed for biodiesel synthesis using poly(dimethylsiloxane–ethyleneoxide) PDMS–PEO as a structure-directing agent. The MgO–Li2O catalysts have a three-dimensional interconnected highly porous structure with bimodal pore distribution that enhances the transesterification reaction. Moreover, Li atoms are not accommodated by alternating MgO slabs within the growth...
This study investigates the use of CaO–CeO 2 mixed oxides as solid base catalysts for the transesterification of Pistacia chinensis oil with methanol to produce biodiesel. These CaO–CeO 2 mixed-oxide catalysts were prepared by an incipient wetness impregnation method and characterized by X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy and scanning electron microscopy...
This study presents a technology for continuous and high-efficiency alkali-catalyzed biodiesel synthesis using a metal foam reactor combined with a passive mixer. A metal foam reactor with higher pore density produces smaller droplets that result in higher efficiency of biodiesel synthesis. Compared with conventional stirred reactors, the time for high methyl ester conversion can be shortened remarkably...
