The hydrogenation of soybean oil has been studied using charcoal-supported palladium catalysts at hydrogen pressures between ambient and 70 psig and at temperatures between 80 C and C in three types of stirred reactor. The catalysts employed were % w/w Pd supported on charcoal and represented differing metal placement on the by: A survey of nickel, platinum and palladium catalysts prepared on silicas, aluminas and mo‐lecular sieves indicated that the nature of such supports contributed importantly to selective hydrogenation of soybean oil.

Nickel‐molecular sieve catalysts provided both high hydrogenation selectivity and lowtrans‐ isomer formation. Some kind of Cited by:   The catalytic transfer hydrogenation of soybean oil by various hydrogen donors and solvents with palladium-oncarbon catalyst was investigated in batch and continuous modes.

Characterization of the catalysts prepared with different silver contents ( wt%) included AAS, XRD, Hg porosimetry, BET and H2 chemisorption measurements. The catalytic activity and selectivity were tested by soybean oil (SBO) hydrogenation under pressure of hydrogen of MPa at ° by: 1.

A statistical method for evaluation of catalysts was used to determine the behavior of palladium catalyst for soybean oil hydrogenation. Empirical models were developed that predict the rate,trans‐isomer formation, and selectivity over a range of practical reaction target iodine value (IV) ranges were studied: one range for a liquid salad oil and the other for a margarine Cited by: The commercial catalysts used in hydrogenation of oil or FAMEs are usually Ni catalysts, which are much cheaper than noble metal catalysts(eg.

Pd). However, more harsh conditions, such as severe hydrogenation pressure(> 20atm)and high reaction temperature(>℃)are re-quired for the Ni catalysts2). In this respect, the mostCited by: 1. Hydrogenation – meaning, to treat with hydrogen – is a chemical reaction between molecular hydrogen and another compound or element, usually in the presence of a catalyst such as nickel, palladium or platinum.

The process is commonly employed to reduce or saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule, often an alkene. Catalysts are required for the reaction to be usable; non-catalytic Feedstock: Unsaturated substrates and hydrogen or.

Introduction:Many scientists (9,16,17) have described the hydrogenation of soybean oil using copper-chromite catalysts of the Adkins type (1,2,7,8,18). Some of these investigators were able to obtain linolenate­ linoleate selectivity ratios (KLe/KLo) of from 6 to 13 and linolenate was hydrogenated to less than 1%.

Hydrogenated Soybean Oil is soybean oil (from soy bean plant (Glycine max)), which is liquid at room temperature, that has been processed by adding hydrogen to make it more saturated. Hydrogenation increases the oil’s stability and raises its melting point so that it is a solid at room temperature.

Hydrogenation is the process of heating an oil and passing hydrogen bubbles through it. The fatty acids in the oil then acquire some of the hydrogen, which makes it more dense.
