| titleOfInvention | Catalyst for producing propylene with methanol of high third second ratio and preparation method thereof is obtained under high-speed |
| abstract | Obtain catalyst for producing propylene with methanol of high third second ratio and preparation method thereof under the present invention relates to a kind of high-speed, this propylene catalyst comprises in mass percentage: the ZSM-5 molecular sieve of 20 ~ 86%; The dispersant of 14 ~ 80%; The P of 0 ~ 5%n 2 on 5 ; The La of 0 ~ 5%n 2 on 3 or Cen 2 on 3 .Its preparation method is that to adopt dispersant to carry out effective dispersion to molecular screen primary powder shaping, then with one or more salting liquids in nonmetal, rare earth metal, carries out modification by the method for incipient impregnation to the shaping molecular sieve of dispersion.The dispersant that the present invention relates to is cheap and easy to get, method for preparing catalyst is simple; For preparing propylene from methanol reaction, reaction temperature 500 DEG C, the mass space velocity of methyl alcohol is 15hn -1 high-speed under, methanol conversion is greater than 99%, and in product, Propylene Selectivity reaches 45.25%, and propylene/ethylene ratio can reach 8.17. |
