Abstract: PURPOSE: Pyrogenic titanium dioxide granulates are provided which are useful as catalyst supports. CONSTITUTION: Such granulates based on pyrogenic titanium dioxide(TiO2) has an average particle diameter of 10 to 150 microns, a BET surface area of 25 to 100 m¬2/g, a pH of 3 to 6 and a tamped density of 400 to 1200 g/l. The granulates are obtainable by dispersing titanium dioxide into water and spray-drying the resulting dispersion, followed by salinization. The silanized granulates have an average particle diameter of 10 to 160 microns, a BET surface area of 15 to 100 m¬2/g, a pH of 3.0 to 9.0, a tamped density of 400 to 1200 g/l, and a carbon content of 0.3 to 12.0 wt%.
