Catalytic hydrogenation of straight vegetable oil using NiMo/ Al2O3 catalyst for biodiesel productionThe attractiveness of biodiesel as an alternative fuel compared to fossil fuels because it has many advantages such as the availability of abundant raw materials, more environmentally friendly, high ...
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

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 ...
