Catalytic Aromatization of Oil Satellite Gases

Abstract

Catalytic aromatization reaction of petroleum gases in a flow catalytic device in the stationary phase of the catalyst (catalyst volume 6 cm³), at 450-600⁰C, at normal atmospheric pressure (P = 0.1 MPa), under the conditions of volumetric velocity of the initial gas mixture 600-1000 h^-1 was held. When the Mo-based catalyst was modified with different metals, the best result was obtained when the content of zirconium in the composition was 1.0%. It was also proved that the activity of the catalyst is high when zinc metal is added to the catalyst in the form of zinc nitrate. As a result of the research, the following optimal conditions for the catalytic aromatization reaction of petroleum gases were selected: catalyst: 5.0% Mo, 2.0% Zn, 2.0% Zr; 0.1MPa; V_NPG = 1000 hours^-1; T = 550⁰C.
