Conclusions
-
1.
Silicates with the crystal structure of type ZSM zeolite were obtained by hydrothermal synthesis in the presence of Al(III), Fe(III), and Cu(II) salts.
-
2.
The selectivity of the aluminosilicates for the aromatic products of the transformation of methanol decreased with an increase in the concentration of Fe(III) and Cu(II); synthesis of aromatic hydrocarbons was not observed on ferrosilicates.
-
3.
It was hypothesized that the introduction of Fe3+ and Cu3+ ions decreases the value of n in the active site of Si(OAl)n(SiO)4−n aluminosilicate, which results in a decrease in the rate of hydrogen redistribution in the unsaturated intermediate compounds formed in the transformation of methanol.
