Do you mean #"propyne"# to #"propylene"#?

Explanation:

And this a reduction reaction with respect to the starting material...

#H_3C-C-=CH + H_2 rarr H_3C-C=CH_2#

And, clearly, a second equiv of dihydrogen could react....

#H_3C-C=CH_2 + H_2 rarr H_3C-CH_2-CH_3#

(the difficulty might be at stopping at the olefin.......)
