Conclusions

  1. 1.

    Modification of the 70% HZHM + 30% Al2O3 HS zeolite composite with Co or Zn + Cr oxides (from 5 to 15%) increases the aromatizing activity of the catalysts in conversion of methanol by 1.5–2 times.

  2. 2.

    The 10% P2O5/70% HZHM + 30% Al2O3 catalytic system is efficient in selective transformation of methanol into C2-C4, olefins (yield >70%).

  3. 3.

    The conditions of their preliminary activation have a significant effect on the catalytic activity of Co- and Zn + Cr-containing zeolite systems; successive air-hydrogen treatment was optimum for these systems.
