SWIM would like to set up something composed of a heavywall roundbottom filter flask, to a hydrogen in line, and a glass stopper greased and securly fit on the top by means of wire (kind of like a champagne bottle), put a spinbar in, set on a mag/hotplate, clamp, and go, if plain stirring would work this would be great!
Barring the filter flask you could substitute with a roundbottom (heavywalled) and fit a vacum adapter on top seal a glass stopper in the female end and setup up like that for hydrogenation.
I always thought for good H2 uptake you need agitation.
