The rate and selectivity found for the hydrogenation reaction of soybean oil using a series of soluble rhodium and iridium-phosphine complexes can be correlated to the number of phosphine ligands coordinated to the metal. This study shows the possibility of obtaining a wide range of products by ...
The hydrogenation of vegetable oil can increase the oxidation stability and shelf life of hydrogenated oils, which is a common industrial method to change the chemical and physical properties of oil. Meanwhile, it is an important catalytic process in oil
It is also a very important reaction in the oil industry. Hydrogenation is used to saturate alkenes and aromatics into saturated alkanes andcycloalkanesrespectively. Similar to saturated vegetable oils, saturated fuels have longer storage life. Heavy residues in refining are hydrogenated byhydrocrackingint...
- 《Journal of the American Oil Chemists Society》 被引量: 114发表: 2001年 Hydrogenation of fats and oils: theory and practice Discusses vegetable and other oils, and considers the hydrogenation technique in detail. Topics covered include the hydrogenation reaction; hydrogenation p... HBW Patterson...
Hydrogenation of vegetable oils has been practiced since the discovery by Normann some 75 years ago and is the major chemical process in the fat and oil industry. Hydrogenation changes a liquid oil to a semisolid fat which has more utility and better flavor stability. The reaction is not a ...
The catalytic transfer of hydrogenation was studied by using 0.5 to 2% of Pd as a catalyst, a limonene:oil ratio of 3:1, and reaction times from 0.5 to 2 hours. Under these conditions, high selectivities for oleic acid and low concentrations of stearic acid were obtained./div...
Vegetable oil is one of the components that is converted from Hydrogenation. Image Credits: shutterstock.com/NaypongStudio How is hydrogen used in hydrogenation? Hydrogen is usually used as reducing agent and will lose its electron in a chemical redox reaction. However, it behaves as an oxidizing...
3. An apparatus for the hydrogenation of a vegetable oil which comprises a reaction vessel having an inlet for said oil, an inlet for hydrogen gas, an outlet for hydrogenated oil, at least one layer of a catalyst structure within said reaction vessel, and means for contacting said catalyst ...
Vegetable oils were hydrogenated in a supercritical single-phase mixture with propane and hydrogen. The reaction was carried out in a small (0.5 ml) fixed-bed reactor and the influence of different process parameters was investigated. In this system both the oil and the hydrogen are dissolved in...
