| 摘 要： | 选择和制备了多种过渡金属单氧化物和复合氧化物催化剂。采用微反-色谱联用装置研究了它们对丙烯氧化制丙烯醛的催化性能。分别考察了反应温度、气体空速、原料配比的影响；其中所研制的金属原子比为2：3：1的Fe－V－Ti复合氧化物催化剂，在空速为10000h~(-1)，反应温度为320℃，C3H6/O2=1:1的条件下，丙烯转化率为78%，丙烯醛选择性为95%，收率为74%，时空产率为5000g·L~(-1)·h~(-1)。

| Abstract: | Several kinds of transition metal single oxide and complex oxide catalysts were selected andprepared. Their catalytic properties for the selective oxidation of propylene to acrolein were investigatedby Ancroreactor-chromatograph combined apparatus. The influences of reaction temperature, spacevelocity and feed composition were experimentally tested. It was found that propylene conversion of78%, acrolein selectivity of 95% and space time yield of 5000 g (L.h)-1 could be obtained with theprepared Fe-V-Ti complex oxide catalyst (metal atom ration Fe:V:Ti=2:3:1). The optimum operatingconditions were reaction temperature of 320'C, space velocity of 10000h-1 and C3H6/O2= 1: 1. |
