摘要

Omega zeolite was dealuminated by hydrothermal and chemical methods to increase its structural stability and improve the defects of its thermal and hydrothermal stability. The structural stability and cracking performance of the modified zeolite were studied. The structural hydrothermal stability was improved after the zeolite was treated under hydrothermal conditions at 800°C for 4 hr. Its crystallinity retention was increased from 38 to 60%. The modified Omega zeolite possessed abundant mesopores, more medium-strong acid, and higher heavy oil conversion.
