摘要
The effect of 0.3 wt % of indium introduced at the peptization and aluminum oxide impregnation stages on the properties of alumina-platinum reforming catalysts has been studied. Modification with indium at the impregnation stage reduces the total acidity of the support to a lesser extent and, as a consequence, the conversion of heptane for the corresponding Pt/In/Al2O3-Cl catalyst. This sample demonstrates the greatest decrease in the selectivity of the hydrogenolysis and hydrocracking reaction alongside with a maximum ratio of i-C5-7/toluene selectivities as compared to the catalysis doped with In at the peptization stage and without doping.
