1.

Catalytic systems based on TsVM high-silica zeolites are active catalysts of ethylene and ethane aromatization. The yields of aromatic hydrocarbons from ethylene on the H form of the TsVM are as high as 75%. The catalyst activity increases in the series Na-TsVM (I) ≪ HNa-TsVM (II) < H-TsVM (III), apparently governed by their acidic function; the catalysts II and III are active in the aromatization of ethane.



2.

The introduction of a dehydrogenating component into the H form of the TsVM, in particular platinum, increases the yield of aromatic hydrocarbons from ethane to 20%.



3.

The aromatization of ethane in the presence of the bifunctional system M/H-TsVM (M=Pt, Pd, Rh) is influenced substantially by preliminary high-temperature treatment of the catalyst (air alone, air and hydrogen, or hydrogen alone).



4.

In the course of ethane and ethylene conversions, the catalytic system M/H-TsVM “evolves, ” with an increase in the yield of aromatic hydrocarbons.
