My textbook introduces the reaction of catalyzed Hydrogenation and later on in the chapter states that all reactions have the ability to proceed forward or backward, yet in the elimination reactions chapter they do not mention this reaction.

So, is it true?

No thats not true.
In many textbooks there are examples of ethene undergoing an addition reaction with a halogen.

No I meant to say is it possible to reverse Hydrogenation.

Oh sorry.
Dehydrogenation you mean?
Yes it is possible by this reaction:

CH3-CH2-CH3 + heat ----> CH2=CH-CH3 + H2

using a platinum catalyst.
