US Patent:

61039497, Aug 15, 2000
Filed:

Sep 27, 1999
Appl. No.:

9/407035
Inventors:

Edward J. Demmel - Newport Beach CA
Albert A. Vierheilig - Richmond Hill GA
Assignee:

Bulldog Technologies U.S.A., Inc. - Wilmington DE
International Classification:

C07C 258
US Classification:

585722
Abstract:

Zeolite/clay/phosphate catalysts can be prepared by a process wherein a composition of zeolite-clay-phosphate is brought to a pH level of about 7. 0 to about 14. The resulting slurry is then age reacted for about 0. 5 to about 24 hours. Thereafter the slurry is dried to produce a zeolite/clay/phosphate catalyst particles that are particularly characterized by their high levels of zeolite stability.

US Patent:

51089793, Apr 28, 1992
Filed:

Feb 25, 1991
Appl. No.:

7/660808
Inventors:

Louis M. Magnabosco - El Torro CA
Edward J. Demmel - Newport Beach CA
Assignee:

Intercat, Inc. - Sea Girt NJ
International Classification:

B01J 2104
B01J 2110
B01J 2310
B01J 2322
US Classification:

502304
Abstract:

Spinels can be synthesized by uniformly dispersing predetermined quantities of ingredient compounds whose particles have sizes no greater than about 5 nanometers in a liquid medium, arresting the ingredient compounds in a solid matrix by spray drying said liquid medium and then calcining the resulting particles to form a solid solution of oxides of said compounds in a crystalline lattice which is substantially free of undesired complex compounds of the ingredient compounds.

US Patent:

54223326, Jun 6, 1995
Filed:

Jul 30, 1993
Appl. No.:

8/099828
Inventors:

Edward J. Demmel - Newport Beach CA
Assignee:

Intercat, Inc. - Manasquan NJ
International Classification:

B01J 2004
US Classification:

502414
Abstract:

Bastnaesite materials and Mg[A] (and/or Al[B]) materials can be chemically reacted by use of reactions wherein a Al[B] ingredient such as alumina is made into a sol by use of a mono-protonic acid before Mg[A] (and/or Al[B]) materials is (are) reacted with the bastnaesite material.

Filed:

Jan 11, 1995
Appl. No.:

8/371402
Inventors:

Edward J. Demmel - Newport Beach CA
Assignee:

Intercat, Inc. - Sea Girt NJ
International Classification:

B01J 0802
B01J 0808
US Classification:

42324401
Abstract:

Bastnaesite materials and Mg A! (and/or Al B!) materials can be chemically reacted by use of reactions wherein a Al B! ingredient such as alumina is made into a sol by use of a mono-protonic acid before Mg A! (and/or Al B!) materials is (are) reacted with the bastnaesite material. The resulting compounds are then used as SO. sub. x catalyst/absorbent materials in fluid catalytic cracking units and/or in fixed bed units.

Filed:

Dec 28, 1995
Appl. No.:

8/579926
Inventors:

Edward J. Demmel - Newport Beach CA
Assignee:

Intercat, Inc. - Manasquan NJ
International Classification:

C10G 912
US Classification:

208 48R
Abstract:

Bastnaesite and magnesium-containing materials can be chemically reacted by use of reactions wherein alumina is made into a sol by use of a mono-protonic acid and then reacted with a magnesium-containing ingredient (e. g. , magnesium acetate) and a bastnaesite ingredient such that, upon spray drying and calcination of the resulting composition, the bastnaesite is chemically reacted with magnesia to form a bastnaesite/magnesia/alumina compound having SO. sub. x activity.

US Patent:

51909022, Mar 2, 1993
Filed:

Jun 4, 1992
Appl. No.:

7/893921
Inventors:

Edward J. Demmel - Newport Beach CA
International Classification:

B01J 2012
B01J 2116
B01J 3728
US Classification:

502 63
Abstract:

Attrition-resistant binders can be prepared by a process wherein a slurry of clay particles is brought to either a low pH level (e. g. , 1. 0 to 3. 0) or to a high pH level (e. g. , 14. 0 to 10. 0) and mixed with a phosphate-containing compound in a concentration of from about 2. 0 to about 20. 0 weight percent. Preferably, the resulting slurry is spray dried and the particulate products of the spray drying are then calcined to produce attrition-resistant binder particles.
