Untersuchungen zur kontinuierlichen Hydrierung von Ölen und Fettsäuren IV: Stoffübergang bei kontinuierlicher Hydrierung

Investigations of Continuous Hydrogenation of Oils and Fatty Acids IV: Migration of Material During Continuous Hydrogenation Material migration takes place more or less in the velocity of the process in every heterogeneously catalyzed reaction. Above all hydrogenation of free fatty acids or fatty acids bound in triglycerides in the three phase system can make material migration valid. The effect of material migration on the reaction kinetic, especially by using high-active catalysts, was verified in a continuous hydrogenation system according to the trickling procedure. The effect of pressure increase up to 0.5 MPa is much higher than in the range of 1-2 MPa. The values of the material migration figure k_m were found in the range of 1.3 to 4.9 · 10⁴ cm · s^?1.
