| 摘 要： | 对HZSM-5沸石进行稀土改性。随着稀土载入量的增多，沸石的总酸量下降，强酸所占比例减少，因而使稀烃与异构化产物增多，提高了汽油辛烷值。稀土载入量应以4%为宜。

| Abstract: | The effect of La 2O 3 modification on HZSM-5 zeolites was studied. As the content of La 2O 3 in the zeolite increased, the acid amount in the zeolite decreased, so did the percentage of strong acids. As a result, alkene and iso-products increased, leading to a rise in gas octane value. The optimal content of La 2O 3 was found to be 4%. |
