摘　　要：在乙苯脱氢LH365催化剂的工业放大生产中,采用将氧化铁的加入量在原配方量的基础上提高3.5%～5.0%,微量元素氧化物(氧化钴、氧化钛、氧化锡、氧化锰等)采用捏合加入方式,催化剂采用两步法干燥及调整催化剂活化工艺等手段,可生产出质量稳定的催化剂。结果表明,该产品达到了合同指标,同时接近小试催化剂的性能。In the mass production of LH 365 ethylbenzene dehydrogenation catalyst,the quality of produced catalyst could keep on stabilization by increasing ferric oxide in the range of 3.5%~ 5.0%,adding microelement,using two-step drying and adjusting activation process.The pact goal of this catalyst was finished,and its level approached to the laboratory test level.
