Ruthenium catalysts supported on multiwalled carbon nanotubes (MCNTs) with different loadings (1% wt, 3% wt, 5% wt) were prepared by reduction with H 2 or NaBH 4 for selective hydrogenation of soybean oil at 338 K and initial pressure of 1.066 MPa. These catalysts were characterized using transmission electron microscopy (TEM), X‐ray powder diffraction (XRD), N 2 adsorption–desorption, and H 2 ‐temperature programmed desorption (TPD) techniques. Ru particles were dispersed more homogeneously on the surface of the nanotubes after being reduced with H 2 than with NaBH 4 . The catalysts with 3% and 5% Ru loadings had higher hydrogenation activity. The NaBH 4 ‐reduced catalyst had higher cis ‐isomer selectivity.
