It hydrogenates the double c=c bond to make it a more 'saturated' oil to natural fat.
Saturated natural fats are harder (more solid) then (unsaturated) natural oils.

How do you harden oil?
HydrogenationDuring hydrogenation, vegetable oils are hardened by reacting them with hydrogen gas at about 60ºC. A nickel catalyst is used to speed up the reaction. The double bonds in the vegetable oils are converted into single bonds. This is the way unsaturated fats can be made into saturated fats.
Fats made when manufacturers add hydrogen to vegetable oils?
Hydrogenated oils
What element do you add to unsaturated vegetable oils to make trans fats?
Hydrogen
Which is the gas that is used for converting vegetable oils into saturated fats?
Hydrogen. The process is called hydrogenation.
How are trans fats formed?
Trans fats are made when manufactures add hydrogen to the fat molecules in vegetable oils.
How do you turn vegetable oils into spreads?
Oils that are normally liquid at room temperature are turned into room temperature solids through hydrogenation. Hydrogen gas is bubbled through vegetable oil in the presence of a catalyst, forcing additional hydrogen bonds onto the hydrocarbon.
Which chemical is needed to harden vegetable oil?
You need available hydrogen to saturate the c=c carbon double bonds. The presence of a catalyst will help move things along, something like nickel.
Why is hydrogen used in making of oils?
Oils by definition are hydrocarbons: compounds of hydrogen and carbon only.
Why are vegetable oils hardened?
because it does
Is edible vegetable oil compound or mixture?
compound
Why use vegetable oils rather that animal oils in edible emulsion?
Animal fats tend to go rancid with time. Vegetable oils will too eventually, but have a longer shelf life.
Can you buy vegetable fat?
Yes. Vegetable oils are vegetable fat. If you want it in a solid form, you can buy vegetable shortening.
