Kinetics of N-ethylcarbazole hydrogenation over a supported Ru catalyst for hydrogen storage

• This reaction is conducted without solvent.
• The apparent kinetics model of the hydrogenation is established.
• The hydrogenation reaction on the catalyst surfaces is the rate controlling step.
• This reaction follows the first-order kinetics.
• The apparent activation energy of this reaction is 30.94 kJ/mol.

The hydrogenation kinetics of N-ethylcarbazole over Ru/γ-Al2O3 was investigated to find the rate of controlling step on the mass transfer-reaction processes. The results showed that the kinetics of reaction was controlled by the hydrogenation reaction on the catalyst surfaces. This reaction followed first-order kinetics with an apparent activation energy of 30.94 kJ/mol. The apparent kinetics model of the hydrogenation was established.
