<p>This invention concerns a zeolite containing rare earth elements and possessing cocrystallization structure of ZSM-5 and ZSM-11, wherein, weight rate of crystal phase structure portion of ZSM-5 and ZSM-11 is from 0.1 to 10. Chemical composition of the prototype zeolite synthesized under anhydrous state is as follows: 0.1-1.0 Na2O, 0.01-1.0 RE2O3, Al2O3. 20-300 SiO2. X-ray diffraction spectral lines of the zeolite Na-type are shown in table 1. The zeolite possesses good acidic hydrothermal stability and anti-impurities contamination ability, and can be used as catalyst in varied hydrocarbon conversion processes.</p> |
