Method Of Preparing Zirconia-Silica Xerogels, The Xerogels, And Xerogel Catalysts
US Patent:
RE31761, Dec 11, 1984
Filed:
Jan 17, 1983
Appl. No.:
6/458520
Inventors:
Robert A. Dombro - Palatine IL
William Kirch - Clinton IA
William Kirch - Clinton IA
Assignee:
Chemplex Company - Rolling Meadows IL
International Classification:
B01J 2702
B01J 2724
B01J 2900
B01J 2724
B01J 2900
US Classification:
502236
Abstract:
A method of preparing large pore volume zirconia-silica catalyst supports, the resulting supports and a method of polymerizing olefins comprising contacting an olefin or mixture of olefins with a catalyst prepared with these supports. The supports are prepared by reacting a zirconium compound of the formula M. sub. 4 Zr(C. sub. 2 O. sub. 4). sub. 4. nH. sub. 2 O, where M is an alkali metal or ammonium ion and n equals 0 to 10, with a silicon compound of the type A. sub. 2 SiO. sub. 3, where A is an alkali metal, in an aqueous solution at a pH equal to at least 11, then adding an acidic solution to a pH of about 5-9 to produce a hydrocogel. The hydrocogel is then aged and washed free of soluble by-products first with water, then with aqueous ammonium nitrate and again with water. The water is removed from the washed hydrocogel by azeotropic distillation or by washing with a water miscible solvent and then calcining the resulting xerocogel.
Copolymerization Of Ethylene
US Patent:
4558105, Dec 10, 1985
Filed:
Dec 7, 1983
Appl. No.:
6/558928
Inventors:
Wayne L. Carrick - Long Grove IL
R. Sven Solvik - Barrington IL
William Kirch - Clinton IA
R. Sven Solvik - Barrington IL
William Kirch - Clinton IA
Assignee:
Chemplex Company - Rolling Meadows IL
International Classification:
C08F 1002
US Classification:
526 68
Abstract:
Ethylene is copolymerized with one or more 1-olefins under conditions of high temperature and pressure in the presence of an inert gaseous ratio modifier. As a result, liquid condensation which contributes to equipment damage and unsafe operation is avoided, and copolymer product density is readily controllable.
Zirconia-Titania-Silica Tergels And Their Use As Catalyst Supports
US Patent:
4791089, Dec 13, 1988
Filed:
Nov 12, 1986
Appl. No.:
6/928586
Inventors:
Robert A. Dombro - Palatine IL
William Kirch - Clinton IA
William Kirch - Clinton IA
Assignee:
Enron Chemical Corporation - Cincinnati OH
International Classification:
B01J 2106
B01J 2010
B01J 2010
US Classification:
502236
Abstract:
A method of preparing a high pore volume, high surface area zirconia-titania-silica tergel useful as an olefin polymerization or copolymerization catalyst support comprises the steps of coprecipitating hydrous zirconia, hydrous titania and hydrous silica, aging and washing the resulting hydrotergel, removing water from the washed hydrotergel and optionally calcining the resulting xerotergel. Resins with predetermined properties such as high melt index, broad molecular weight distribution, high weight swell, etc. can be produced from catalysts of the chromium or Ziegler type based on these supports.
