以液体有机化合物如9-乙基咔唑的形式储氢是一种相对新颖的方法。本文研究了Raney-Ni催化剂上9-乙基咔唑加氢反应动力学，考察了反应温度、压力和催化剂浓度对传质-反应过程的影响。结果表明，反应动力学受催化剂表面化学过程控制。加氢反应符合一级反应动力学，表观活化能为65.17KJ/mol。建立了加氢反应的表观动力学模型。
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 65.17KJ/mol. The apparent kinetics model of the hydrogenation was established.
