【摘要】 建立了苯与十二烯烷基化悬浮床催化精馏过程的动态平衡级模型,模型对过渡过程达到定态时的系统性能预测与定态实验数据和定态模拟结果吻合良好.利用模型模拟,就苯的进料位置、苯和混合烃进料流量的正向扰动对系统性能的影响进行了研究.结果表明:在给定条件下系统仅存在一个定态;反应段最后一块塔板是苯的最优进料位置;系统对于所施加量级的扰动是稳定的,其抗干扰能力很强.更多还原

【Abstract】 A dynamic equilibrium stage model of the suspension catalytic distillation process for alkylation of benzene with C₁₂olefins is developed.The prediction for steady-state based on the proposed mathematical model agrees with the steady-state experimental data and simulation results well.The stationary and dynamic models developed are used to simulate the influence of the location of benzene feed stream, disturbances of benzene and mixed hydrocarbon feed flow rates upon the suspension catalytic distillation system.Only one steady-state can exist in the system for the given conditions,and the last stage in reaction section is the optimal location of benzene feed stream.The system is stable for the imposed disturbances,and its anti-disturbance ability is very strong.更多还原
