In this work,the evaporation of the liquid cyclohexane is used to remove the heat of reaction in a novel phase transition reactor for hydrogenation of benzene to form cyclohexane under elevated pressure up to 3 0 MPa.The reactor is of fixed\|bed with Pd catalyst,20 mm in diameter and 100 cm in height.The operation conditions are 150 ℃ in inlet temperature,1 1~6 9 h -1 in LHSV and 330~1910 in volume ratio of hydrogen to liquid.The experimental results show that the conversion of benzene is...

In this work,the evaporation of the liquid cyclohexane is used to remove the heat of reaction in a novel phase transition reactor for hydrogenation of benzene to form cyclohexane under elevated pressure up to 3 0 MPa.The reactor is of fixed\|bed with Pd catalyst,20 mm in diameter and 100 cm in height.The operation conditions are 150 ℃ in inlet temperature,1 1~6 9 h -1 in LHSV and 330~1910 in volume ratio of hydrogen to liquid.The experimental results show that the conversion of benzene is over than 99 99% and the yield of cyclohexane also over than 99 9%.\;A mixture of benzene(accounting for 15%~25%) and cyclohexane is used as feed to prevent the abrupt temperature rise in the bed.The bed axial temperature distribution indicates the phase transition behavior of the liquid feed which varies from the liquid state,via the mixed phase,and eventually to the gaseous state.So there exists a three phase's regime in the catalyst bed.

文章提出了依靠相变蒸发吸收反应热 ,同时解决移热和加速反应等问题的新型化学反应器并开展了实验研究。实验在加压下进行 ,催化剂床层高度为 1 0m ,反应器内径为 0 0 2m ,苯加氢生成环己烷为研究体系 ,实验中采用气液并流向上流动的方式通过催化剂床层。在操作条件 :p =0 5~ 3 0MPa、θ =1 50℃、液体空速 =1 1~ 6 9h- 1 、氢油体积比 =30 0~ 1 91 0下 ,苯的转化率及环己烷的收率均可达到 99 9%以上。为了防止反应器内发生飞温 ,实验采用苯与环己烷的混合物作为原料 ,其中苯的质量分数为 1 5 %~ 2 5 %。随着反应物料不断进入反应器 ,液相物料吸收反应放出的热量而蒸发 ,因此在适当的操作条件下床层内可同时存在液相反应区、气液两相区和气相反应区
