Abstract Soybean oil was hydrogenated continuously in the presence of nickel catalysts. The iodine value of the products was varied by changing the oil flow rate and temperature of the reaction. Sulfur‐promoted nickel catalyst increased the selectivity for linolenate hydrogenation, but formed much higher proportions of trans isomers. Linoleate selectivity improved with temperature with both nickel and sulfur‐promoted nickel catalysts, but trans isomerization also increased. The feasibility of this continuous reactor system was demonstrated as a practical means to prepare hydrogenated stocks of desired composition and physical characteristics at high throughput.
