Реферат: Monometallic indium-doped Pt/Al2O3catalysts for n-heptane reforming were studied using the low-temperature adsorption of nitrogen, XRD, NH3-TPD, and H2-TPR. The introduction of indium at the step of aluminum hydroxide peptization increases SBET of the produced alumina and decreases its size of coherent scattering region (CSR). The H2-TPR data testify to a strong Pt-In interaction, probably leading to the formation of Pt-In alloys. The NH3-TPD results demonstrate the addition of indium to alumina decreases the fraction of strong and medium acid sites. In n-heptane reforming, the presence of indium enhances the catalyst selectivity for isomers and decreases the selectivity for hydrogenolysis and aromatization products. Such effects are most pronounced for the Pt/Al2O3InH-Cl sample with indium hydroxide used as the precursor.
