本文对含有不凝组份的苯和乙烯烷基化催化精馏过程进行了计算机模拟。以少量实验验证计算机模拟的可靠性。在得出计算机模拟结果基本可以表述催化精馏过程实际清况后,利用计算机模拟方法优选出最佳工艺条件。而后又用实验装置对所选最佳工艺条件进行验证。从而证明可利用实验与计算机模拟相结合的方法对催化精馏进行工艺条件的优选。 In this paper, a computer simulation of catalytic alkylation of benzene and ethylene with non-condensable components was carried out. A small number of experiments to verify the reliability of computer simulation. Computer simulation results obtained in the basic state of the catalytic distillation process can be expressed, the use of computer simulation method to optimize the optimal process conditions. Then use the experimental device to verify the optimum process conditions. Thus it can be proved that the optimal conditions for catalytic distillation can be obtained by the combination of experiments and computer simulation.
