“…CTH is a technology for hydrogenating soybean oil in which hydrogen is replaced by hydrogen donors. [15] Yu et al [16] studied the improvement of soybean oil hydrogenation through the CTH method, which does not require high-pressure operation and has the advantages of being safe, simple, and environmentally friendly.…”

To provide a new, safe, and efficient way to produce hydrogenated oils, a loaded Pd/MWCNTs catalyst is studied and applied to the catalytic transfer of soybean oil under ultrasound conditions. Pd is loaded onto multiwalled carbon nanotubes (MWCNTs) by impregnation, and the Pd loading is ≈0.8%. Through X‐ray diffraction analysis, it is found that the characteristic emission peaks of Pd appear at the 2θ = 40.3°, 46.7°, and 68.2° locations. Moreover, transmission electron microscopy reveals that the catalyst is uniformly dispersed and less agglomerated. X‐ray photoelectron spectroscopy spectra show that Pd is successfully loaded onto MWCNTs. Pd/MWCNTs catalyst is then applied to the catalytic transfer of hydrogenated soybean oil. The results show that when ultrasonic power is 100 W, catalyst concentration is 2.0% w/w, hydrogenation temperature is 80 °C, donor concentration is 0.32 mol/50 mL H2O, the maximum hydrogenation conversion is 31.97%, and the content of trans‐fatty acid is only 1.52%. Pd/MWCNTs catalyst can be recycled for four times in catalytic hydrogenation of soybean oil, and the activity of the catalyst decreases to 78.5% at the fourth time. Practical Application (PA): In this study, Pd is well loaded on multiwalled carbon nanotubes (MWCNTs) by means of ultrasound. The ultrasonic assisted Pd/MWCNTs catalyst catalyzes the transfer hydrogenation of soybean oil. The hydrogenation conversion rate of soybean oil is significantly improved by this method, and the content of trans fatty acid in hydrogenated soybean oil is low. The Pd/MWCNTs can be recycled for four times as a catalyst.
