Аннотация:Conversion of oxygenates to aromatic hydrocarbons in the syngas medium in the presence of a commercial zeolite-containing catalyst was studied. The infl uence of pressure on aromatization of dimethyl ether and
ethanol was examined. At 400°С, an increase in the pressure from 0.1 to 3.0–10.0 MPa leads to a sharp increase in
the yield of aromatic compounds. Dimethyl ether and ethanol, which are isomers belonging to different classes of
compounds, were compared as substrates in conversion to aromatic hydrocarbons. At elevated pressure, dimethyl
ether compared to ethanol exhibits higher selectivity in formation of the desired synthesis products, allowing
synthesis of liquid hydrocarbons with increased content of arenes.
