Abstract
The effect of modification of sulphated zirconium dioxide by aluminium oxide additives on its texture, phase composition, acidity and catalytic properties in the process of isobutane alkylation with butanes was studied. It is shown that the best catalytic properties are those of the SO42-−ZrO2−Al2О3 sample with aluminium oxide content 20 mass %, annealed at a temperature of 650 °C.
