Изомеризация н-гексана на Pt/SO4/ZrO2 катализаторах, нанесенных на Al2O3. Влияние добавок олова

Abstract

The studies dealt with the influence of the precursor of Sn(IV) added to aluminum hydroxide at the stage of peptization on the performance of n-hexane isomerization in the presence of supported Pt/SZ/Al₂O₃(Sn) catalysts. It was shown that particles of the active tetragonal phase t-ZrO₂ supported on Al₂O₃(Sn) were 3.2, 8.3 and 8.4 nm in size when hydroxide, chloride and sulfate of Sn(IV), respectively, was used. The smaller active phase particles in size, the larger specific surface area and, as a result, the catalyst is more active to isomerization of n-hexane.
