添加剂在加氢精制催化剂中作用的研究进展
Progresses in Research of Additives for Hydrorefining Catalysts
摘要
Abstract
Secondary additives(such as fluorine,boron and phosphorus) and complexing agents (such as citric acid,nitrilotriacetic acid and ethylenediamine tetraacetic acid) are main additives for hydrorefining catalysts.The effects of the two kinds of additives on the hydrorefining catalysts were introduced,and the way of the additives introduction,the effects and the action mechanism were discussed.The main roles of the additives could be concluded as follows:weakening the interaction between metals and supports,promoting the dispersion of metals on the surface of supports,improving the structure of the active phases of the catalysts and strengthening the acidity of the catalysts.However,it was still controversial how the additives enhanced catalyst acidity and affected the metal dispersion.关键词
