Production Of High Strength Alumina Spheres By Hydrogelling Corresponding Slurries
US Patent:
4198318, Apr 15, 1980
Filed:
Nov 24, 1978
Appl. No.:
5/963594
Inventors:
Donald E. Stowell - Oklahoma City OK R. Tom Jackson - Ponca City OK Larry L. Bendig - Ponca City OK
Assignee:
Conoco, Inc. - Ponca City OK
International Classification:
B01J 2104, B01J 3508, C01F 702
US Classification:
252448
Abstract:
Alumina spheres having high crush strength are produced by hydrogelling low viscosity acidified alumina slurries in a surfactant-containing ammonia solution, said slurries being inserted into the ammonia solution dropwise.
High Pore Volume Alumina Powders
US Patent:
4218413, Aug 19, 1980
Filed:
Dec 18, 1978
Appl. No.:
5/970282
Inventors:
Donald E. Stowell - Oklahoma City OK John F. Scamehorn - Austin TX Larry L. Bendig - Ponca City OK
Assignee:
Conoco, Inc. - Ponca City OK
International Classification:
B01J 202
US Classification:
264 13
Abstract:
A method for increasing the pore volume of alumina powder produced by spray drying alumina slurries by heating the slurry to a temperature near the boiling point of water and a pressure up to the critical point of water then introducing the slurry to a spray drying chamber through a small orifice, thereby creating a backpressure in excess of slurry vapor pressure and up to the critical point of water.
Production Of Low Loose Bulk Density Alumina
US Patent:
4177251, Dec 4, 1979
Filed:
Oct 23, 1978
Appl. No.:
5/954042
Inventors:
Larry L. Bendig - Ponca City OK Donald E. Stowell - Oklahoma City OK Laura A. Starks - New Orleans LA
Assignee:
Conoco, Inc. - Ponca City OK
International Classification:
C01F 702
US Classification:
423628
Abstract:
Alumina having a low loose bulk density is obtained by hydrolyzing aluminum alkoxides with water in the presence of lithium hydroxide or lithium salts yielding lithium ions. The amount of density reduction is proportional to the amount of lithium ion present.
