对多相态条件下环己烷的连续脱氢反应进行研究,考察盐浴温度、进料速率以及催化剂(Raney-Ni)用量对环己烷连续脱氢反应的影响。研究发现:当盐浴温度370℃,进料速率25mL/h,催化剂用量3g时,环己烷连续脱氢反应系统的综合性能达到最佳,其产氢速率可达27mL/min,生成氢气的纯度为88%,环己烷的脱氢转化率为8.2%。对290～410℃盐浴温度下环己烷连续脱氢表观反应动力学的研究表明,反应的表观活化能约为12.57kJ/mol。
The continuous dehydrogenation of cyclohexane under multi-phase conditions was studied. The effect of salt bath temperature, feed rate and the amount of catalyst (Raney-Ni) on the continuous dehydrogenation of cyclohexane was investigated. The results show that when the temperature of salt bath is 370 ℃, the feed rate is 25mL / h and the amount of catalyst is 3g, the continuous dehydrogenation reaction system of cyclohexane achieves the best performance. The hydrogen production rate reaches 27mL / min, The purity was 88%, and the dehydrogenation conversion of cyclohexane was 8.2%. The apparent reaction kinetics of continuous dehydrogenation of cyclohexane at salt bath temperature from 290 ℃ to 410 ℃ showed that the apparent activation energy of the reaction was about 12.57kJ / mol.
