Annotation:

One of the largest processes for producing high-octane additives and gasolines is catalytic reforming, which is based on the processing of straight-run gasoline in the presence of hydrogen-containing gas. Currently, in accordance with the requirements of EURO-5 and GOST 32513-2023, the catalytic reforming process is focused on producing gasoline high-octane fractions with a high content of isoparaffinic hydrocarbons, rather than aromatic ones. The authors of the article present research data on the process of the straight-run gasoline fraction refining in the absence of hydrogen-containing gas using an aluminosilicate zeolite-containing catalyst. The process of refining the straight–run gasoline fraction was studied on a standard laboratory installation with a stationary catalyst layer at a temperature of 350...500 °C, a pressure of 0,1 and 1,0 MPa and a volumetric feed rate of 1,0 hr^–1.

Studies of the catalyst stable activity under the influence of multiple cycles of coking–regeneration were carried out, followed by testing in the process of hydrogen-free refining of the straight-run gasoline fraction. According to the study results, the stable activity of the catalyst and the conditions for the process of hydrogen-free refining of the straight-run gasoline fraction were determined.
