The electronic state of promoted Pt/Al2O3 catalysts and their activity in the dehydrocyclization of sec-butylbenzene

The catalytic dehydrocyclization of sec-butylbenzene on a modified SB-RD-150 industrial catalyst has been studied. The Pt/Al2O3 catalyst has been modified by promotion with Pd, Ir, Co, Re, Au; the metal concentration was 0.6%. Some correlations between the electronic properties of the metallic components in the promoted catalysts and their catalytic acivity in the dehydrocyclization of sec-butylbenzene have been estableshed.
