前言在润滑油加氢补充精制的铁-钼催化剂的研制过程中发现,在实验室用浸渍法制得的催化剂强度较好,锭片无裂纹,浸后硝酸铁液透明;但是用同样制备工艺的工业放大所得催化剂强度差,锭片龟裂严重,浸后硝酸铁液混浊。 Preface In the process of research and development of iron-molybdenum catalyst for hydrotreating and refining of lubricating oil, it was found that the strength of the catalyst prepared by the impregnation method in the laboratory is good, the tablet has no crack and the ferric nitrate solution is transparent after the immersion; however, Industrial amplification catalyst obtained poor strength, severe cracked tablets, immersion ferric nitrate cloudy.
