Abstract

Abstract The hydrogenation of oleic acid to stearic acid, over hydrogen storage intermetallic compound LaNi 4.8Cu 0.2 as catalyst, at 90°C and 0.5 MPa hydrogen pressure was investigated. It is found that the LaNi 4.8Cu 0.2 alloy has very good activity, when it is hydrided before the addition of oleic acid. The hydriding process is rather quick and is generally completed in a few minutes. Based on the results obtained, a tubular reactor for continuous operation was designed, tested and proved to work well.
