| Abstract: | 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. |
