采用微反--色谱联用装置,对丙烯在 Bi-Co-Mo 氧化物催化剂上选择性氧化的上下限操作体系分别进行了动力学研究。得出了最佳操作条件,其中最佳温度对两种系统都是330℃,而最佳空速对于上限操作(丙烯浓度=13%)为13500h~(-1) ,对下限操作(丙烯浓度=1. 5%)为18000h~(-1) 。对两种体系分别由实验数据导出了动力学方程。 The kinetics of the upper and lower operation systems for the selective oxidation of propylene over Bi-Co-Mo oxide catalysts was investigated by a micro-reverse-chromatographic device. The optimum operating conditions were obtained where the optimum temperature was 330 ° C for both systems and the optimum space velocity was 13500 h -1 for the upper limit operation (propylene concentration = 13%) and for the lower limit operation (propylene concentration = 1.5%) is 18000h ~ (-1). The kinetic equations were derived from the experimental data for both systems.
