Olefins can be hydrogenated by

Olefins can be hydrogenated by reacting them with hydrogen gas in the presence of a catalyst, typically a metal such as palladium, platinum, or nickel. This process adds hydrogen across the double bond of the olefin, converting it into a saturated alkane. Hydrogenation is commonly used in various industrial applications, including the production of fuels and the modification of fats and oils. The reaction conditions, such as temperature and pressure, can significantly influence the efficiency and selectivity of the process.
