| 英文摘要 | During the strong exothermic reaction in the fixed-bed reactor, the hot spot temperature of the reactor is sensitive to the change of operating parameters, which can easily cause flying temperature, resulting in a decrease in conversion rate and affecting catalyst life. In order to enhance the synergy of heat and mass transfer and chemical reaction in a fixed-bed reactor for carbonylation, a one-dimensional pseudo-homogeneous heat transfer model was established to investigate the effects of operating parameters on bed hot spot temperature, reaction conversion and bed temperature rise. The presented method not only reflects the synergistic effect of heat and mass transfer and reaction, but also has clear interrelation and convenient algorithm. Under the experimental application conditions, the catalyst particle diameter is less than or equal to 1.5 mm. The reactor inlet temperature / coolant oil temperature should not only meet the requirements of thermal stability of the bed, but also make the reaction conversion and bed temperature rise within a reasonable range. The simulation results show that with the increase of bed inlet temperature, good conversion rate and small bed temperature rise can be obtained by reducing the coolant oil temperature. On this basis, the effect of ethylene oxide inlet concentration on the conversion and bed temperature rise was investigated. This study can provide a basis for the selection of operating parameters such as catalyst particle diameter, bed inlet temperature, coolant oil temperature and bed inlet concentration for the fixed-bed reactor to meet the conversion requirements and reasonable bed temperature rise. 漏 2021, Editorial Board of CIESC Journal.
