Abstract
A method of manufacturing high surface area spheroidal alumina particles. A finely divided eta alumina is admixed and suspended in an alumina hydrosol and the mixture thereafter converted to spheroidal particles comprising eta and gamma alumina by the oil-drop method. The alumina spheres are particularly useful as a high surface area support or carrier material for catalytic components, and as a high surface area adsorbent.
