Abstract

In this article, the kinetics of the synthesis of benzene-free aromatic hydrocarbons by aromatizing hexane with the modified 2%La/NYuKTs-40 and 2%La*2%Cu*8%Zn/N-YuKTs-40 catalysts in the presence of catalysts was studied. 2%La*2%Cu*8%Zn/N-YuKTs-30 for a catalyst with higher catalytic activity was selected for aromatization of hexane with a linear structure to obtain aromatic hydrocarbons Ekaj 2%La*2%Cu*8%Zn/N-YuKTs-20 was found to be smaller than the catalyst with higher activity selected for the aromatization of hexane with a linear structure to produce aromatic hydrocarbons. 2%La*2%Cu*8%Zn/NYuKTs-30 and 2%La*2%Cu*8%Zn/N-YuKTs-20 with higher catalytic activity were selected for aromatization of hexane with a linear structure to obtain aromatic hydrocarbons the process of improvement of low-octane 85-1800С gasoline fractions on catalysts was studied at atmospheric pressure, in the temperature range of 400-5000С, without hydrogencontaining gas circulation. It was found that the 2%La*2%Cu*8%Zn/NYuKTs-30 catalyst with high catalytic activity, selected for the catalytic aromatization of hexane with a linear structure, produces a high-octane catalyst with aromatic hydrocarbons as its main.
