Laboratory-scale continuous hydrogenation: copper catalysis

Snyder, J.M. | Scholfield, C.R. | Mounts, T.L.
Soybean oil was partially hydrogenated with Cu catalyst in an isothermal, concurrent, flow type reactor to reduce linolenate content. Reaction proceeded at 1 atm outlet pressure; the parameters of temperature, catalyst concentration and oil flow rate (residence time) were varied. The reactor was designed to permit sampling at points along its length. Intermediate and final samples were analyzed to give total characterization of the partially hydrogenated oil. Data thus obtained were used to model and simulate the continuous hydrogenation kinetics. Linolenate selectivity is high and variations in reaction parameters appeared to have little effect. Specific isomerization values were increased as catalyst concentration increased but were unaffected by temperature and oil flow rate. Conjugated diene formation went through a maximum as the hydrogenation proceeded. Results of the Cu catalyzed continuous hydrogenations were compared to those of batch hydrogenations using the same reaction parameters.
