Abstract
The paper continues a series of studies aimed at developing a new approaches to the regeneration of coked bimetallic heterogeneous systems. The comparison of activity of the three samples of industrial n-heptane reforming catalyst Ru-125 (Pt-Re/γ-Al2O3) was held: fresh (A), discharged from an industrial reactor (B) and the sample B after the ozone treatment in supercritical carbon dioxide (C). It was found that the sample (B) substantially deactivated: conversion of n-heptane and the reforming product yield significantly lower than on the fresh catalyst. After the sample (B) was treated in O3/SK-CO2 the conversion value of n-heptane is not only return to the level of fresh sample (A), but it exceeds in 1,2 times. The qualitative composition of the products on the samples (A), (B), (C) is practically the same but there is change in the ratio of individual products. It is concluded that the regeneration of using ozone is promising for further development and scaling.
