摘要
以Ru/C为催化剂,通过改变温度、压力、搅拌速度等因素对乙基咔唑的催化加氢性能进行研究,并对其加氢动力学进行初步探索。研究表明:乙基咔唑的最佳加氢反应条件为6MPa、423K、0.8g Ru/C、750r/min,在此条件下,乙基咔唑的储氢密度约可达4.73%(质量分数);乙基咔唑加氢反应的表观活化能为19.91kJ/mol。
The hydrogenation of N-ethylcarbazole over Ru/C catalyst was conducted to study the effect of temperature, pressure and rotating speed on the hydrogenation process, and the hydrogenation dynamics was investigated preliminarily. The results show that the optimum reaction condition is 6MPa, 423K, 0. 8g Ru/C, 750r/min, and the corresponding hydrogen storage capacity could reach 4. 73% (mass fraction) approximately and the apparent activation energy was 19.91kJ/mol.
