摘要
本文用草酸对USY型分子筛进行改性研究,用XRF、XRD等手段对改性分子筛样品的结构进行了表征.重油催化裂化实验结果表明,加入草酸可以提高分子筛的催化性能.
Modification of USY zeolite was carried out with the oxalic acid treatment. The structure of the USY zeolite before and after modification was characterized by XRF, XRD etc. The effects of oxalic acid treatment on the catalytic performance of USY zeolite for heavy oil cracking were studied. The results showed that the proper quantity of oxalic acid addition could improve the catalytic performance of USY zeolite.
