Abstract:
The catalytic behavior of Pd-Mg/SiO2 for the partial hydrogenation of diunsaturated
FAMEs (C18:2) to improve the oxidative stability of soybean oil-derived biodiesel was
studied. The hydrogenation activity and cis-monounsaturated FAME (cis-C18:1) selectivity
of the catalyst were compared with that of the pure silica support (SiO2) at various C18:2
conversion levels, i.e., 12% and 36%. The SiO2 and Pd-Mg/SiO2 catalyst were characterized
using X-ray diffraction (XRD), transmission electron microscopy (TEM), N2 adsorptiondesorption,
X-ray photoelectron spectroscopy (XPS), and CO pulse chemisorption. The
FAME composition, oxidative stability and cold flow properties of biodiesel and partially
hydrogenated biodiesel were determined using gas chromatography (GC-FID), Rancimat
method, and cold flow testing. The contents of FAME composition in partially hydrogenated
biodiesel using SiO2 was hardly altered during 4-h reaction owing to the lack of palladium
(Pd) active sites. At 12% C18:2 conversion, the hydrogenation rapidly performed due to an
abundance of the vacant Pd sites, leading to the high turnover frequency (TOF; 24228 h-1);
however, it was then decreased at 36% C18:2 conversion (16863 h-1). The amount of cis-
C18:1 and trans-C18:1 was increased with increasing the hydrogenation of C18:2 content.
The oxidative stability of partially hydrogenated biodiesel using Pd-Mg/SiO2 was noticeably
improved.
