摘要：借助Aspen Plus软件对钛硅分子筛法合成环氧丙烷全流程工艺进行模拟,并对主要的塔设备进行模拟计算和参数优化,考察了返混和温度对过氧化氢转化率和环氧丙烷选择性的影响,并采用实验对模拟结果进行验证。结果表明:采用双釜串联能有效抑制返混,提高过氧化氢转化率和环氧丙烷选择性;随着温度升高,过氧化氢转化率上升,环氧丙烷选择性下降;模拟结果与实验结果相符。
The process of synthesis of propylene oxide over titanium silicalite （TS-1） catalyst was simulated by software Aspen Plus, the effects of backmixing and temperature on the conversion of H2O2 and the selectivity of propylene oxide were investigated, and the results of simulation were verified by experiments under the same conditions. The results showed that the double reactors in series could inhibit the backmixing and increase the conversion of H2O2 and the selectivity of propylene oxide. The conversion of H2O2 increased and the selectivity of propylene oxide decreased with the increase of temperature. The results of simulation agreed well with the experimental results.
