Abstract
Hydrogen storage in form of liquid organic hydrides, e.g. 9-ethylcarbazole, is a relatively novel method. In the present work, the hydrogenation kinetics of 9-ethylcarbazole over Raney-Ni catalyst was studied by investigating the influences of the reaction temperature, pressure and catalyst concentration on the mass transfer-reaction processes. The results show that the kinetics of reaction is controlled by the chemical process on the catalyst surfaces. The hydrogenation reaction followed first-order kinetics with an apparent activation energy of 65.17 KJ/mol. The apparent kinetics model of the hydrogenation was established.
