摘  要:为了给工业磁稳定床反应器的设计提供科学依据,笔者建立了己内酰胺水溶液加氢精制的液-固磁稳定床反应器数学模型.采用Range-Kuta法对模型进行计算,处理能力6 kt/a的中试液-固磁稳定床反应器的模拟结果与实验结果的平均相对偏差为13.2%.对处理能力70 kt/a的工业磁稳定床反应器进行了模拟.模拟结果表明,反应器内径为0.9~1.0 m时,经磁稳定床加氢,己内酰胺水溶液的PM值(Permanganate number)从50 s提高至3000 s.For the purpose of providing scientific bases for the design of industrial magnetically stabilized bed reactor, a mathematical model of liquid-solid magnetically stabilized bed reactor for the hydrofinishing of caprolactam solution was established. The model was calculated with Range-Kuta method. A pilot plant of magnetically stabilized bed reactor with the capacity of 6 kt/a was simulated, and the simulative results fitted the experimental results well with a mean relative deviation of 13.2%. A simulative calculation was also carried out for a magnetically stabilized bed reactor with the capacity of 70 kt/a. The results showed that the PM number (Permanganate number) of caprolactam solution increased from 50 s to 3000 s through magnetically stabilized bed reactor hydrogenation process, as the reactor diameter was in the range of 0.9-1.0 m.
