Abstract:
The textural and acid–base characteristics of initial alumina and alumina modified with acetic acid
at different concentrations (from 0.83 to 17.4 mol/L) were studied. It was found that treatment with acetic
acid did not exert significant effects on the texture characteristics and phase composition of the supports.
According to the IR-spectroscopic data on adsorbed CO, an increase in the concentration of mediumstrength Lewis acid sites and an increase in the total acidity of the modified supports were observed, as compared with those of the starting alumina. Among the Pt‒Re systems, a catalyst based on the support treated
with acetic acid at a concentration of 1.67 mol/L exhibited the highest activity in n-heptane reforming due to
an optimal composition of the acid sites of the support.
