摘要：

The effects of the method of introducing iron and iron concentration on the acid properties, catalytic activity, and stability of a zeolite in methanol conversion to hydrocarbons were studied. The state of active sites in the zeolite depends on the distribution of the metal in its structure, which depends on the method of zeolite modification. The addition of iron to zeolite increased the catalyst run time between regenerations, and the samples in which iron was introduced at the stage of hydrothermal synthesis exhibited the maximum catalytic stability.
