摘要
在用直径为２．７～３．０ｍｍ球型ＦＸ－０１催化剂填充的用于合成异丙苯三相鼓泡反应器中，其苯、丙烯反应生成异丙苯过程为外扩散控制［１］。欲提高反应程度，必须从控制步骤入手。在１４０、１６０和１８０℃三个温度下，比较了０．９、１．５ＭＰａ下的反应程度，结果为低压下反应程度高；在此三个温度条件下，做了苯质量空速１、２、３和３．８ｈ－１时的对比试验。结果表明，空速增加，反应程度提高。
The reaction of benzene with propylene to synthesize isopropyl benzene carries out in the triphasic bubble reactor packed with φ2 7～3 0mm spherical FX 01 catalyst The reaction is controlled by external diffusion The most important factor in increasing the conversion of the reaction product is to reduce resistance of the controlling step The influence of pressure,space velocity on the reaction has been studied at different temperatures Comparison of reaction made under 0 9 and 1 5MPa and at 140,160 and 180℃ show that the extent of the reaction is greater.under lower pressure At the above three temperatures,and with space velocity of 1,2,3 and 3 8h -1 ,the extent of reaction increases with increasing space velocity The underlying causes have been discussed
