摘　　要：以Pd／γ-Al2O3为催化剂，在101kPa473～533K的条件下，系统研究十二氢乙基咔唑的脱氢性能，考察反应温度和催化剂用量对反应速率和转化率的影响；同时还对十二氢乙基咔唑的脱氢动力学进行初步探索。结果表明，十二氢乙基咔唑的放氢温度低于传统有机氢化物，在493K时，释放出89．43％储存的氢气，脱氢产物主要为乙基咔唑；脱氢表观活化能为61．14kJ／mol。In the present work, the dehydrogenation of dodecahydro-N-ethylcarbazole over Pd/γ-Al2O3 catalyst was studied by investigating the influences of the reaction temperature and catalyst concentration on reaction rate and conversion rate, at the same time, the dehydrogenation dynamics of dodecahydro-N-ethylcarbazole was discussed initially. The results showed that the dehydrogenation reaction temperature of dodecahydro-N-ethylcarbazole is lower than the traditional organic hydrides, at 473 K, 80.72% of hydrogen storage can be released, dehydrogenation products are mainly N-ethylcarbazole, and the apparent active energy of dehydrogenation is 61.14 kJ/mol.
