The infl uence exerted by the kind of the tin precursor [SnCl4·5H2O or H2Sn(OH)6] and by the Cl– content (0.86–0.97 wt %) on the adsorption and catalytic properties of Pt sites in Pt/Sn–Al2O3–Cl heptane reforming catalysts was studied. The kind of the Sn precursor does not significantly influence the dispersity of the Pt particles. Among Pt sites, electron-defi cient Pt forms prevail in the presence of Sn and at increased Cl– content. The acidity of the surface of the Pt/Al2O3–Cl catalyst increases on introducing Sn and with an increase in the Cl– content owing to strong acid sites. The catalyst containing 0.2 wt % Sn from H2Sn(OH)6 and 0.86 wt % Cl– exhibits the highest selectivity of the heptane aromatization and slightly increased selectivity of the С1–4 gas formation.
