Feb 13, 2019 · The Catalyst. The reaction between hydrogen (H 2) gas and an alkene (a carbon-carbon double bond) requires an active metal catalyst.A catalyst increases the reaction rate by lowering the activation energy of the reaction. Although the catalyst is not consumed in the reaction, it is required to accelerate the reaction sufficiently to be observed in a reasonable amount of time.

The agitation system has the task of intensifying the mass/liquid transfer as hydrogenation reactions are usually mass-transfer limited. Additionally, the agitator must enhance the heat transfer to cool the reactor system. The vessel content must also be so homogenized as to avoid uneven temperature and concentration profiles during the hydrogenation process.
