Aluminiumoxidekogels die een grote mechanische bestendigheid tegen schokken hebben en hun vervaardigingswerkwijze. |
摘要 |
Porous spheroidal alumina particulate solids that comprise an alumina filler in an amount of about 0.1% to about 25% by weight of Al2O3 and have a mechanical resistance to shocks measured by spheres impacting against a target at the speed of 20 m/s such that the fines fragmentation percentage, of a size of less than 50% of the average size of the initial spheres, is less than 5% by weight. Preparation of these spheres by coagulation in drops from an oil-in-water-type emulsion. Application of these spheres as a catalyst substrate or as an adsorbent. |
