Исследование технологии высокооктановых компонентов бензинов с улучшенными экологическими свойствами

Keywords: catalytic reforming, hydroisomerization, reduction of aromatic hydrocar-bons in gasolines, hydrogenation of six-membered naphthenes into five-membered.

Abstract
Today, there are many options for recovering benzene. One such process is reformate hydroisomerization.
The article presents a study of the effect of the hydroisomerization parameters of the NK-115 ° C fraction of the reformate of the LCh-35-11 / 600 installation, obtained in hard mode, on the detonation parameters of hydroisomerizate and gasoline, obtained by mixing the hydroisomerizate with the residual reformate fraction of 115 ° С — c.k.
The study was conducted on a pilot installation with a circulation of hydrogen-containing gas at a temperature of 200-430 ° C, a pressure of 3 MPa and a volumetric feed rate of 2 h-1. The process was carried out using IP-62 alumina-platinum catalyst.
The obtained components of gasoline in terms of antiknock properties are close to the initial reformat or exceed it. The aromatic content in them is reduced by 10% of the mass. and more due to the hydrogenation of lower aromatic hydrocarbons.
