Filed:

Mar 23, 2000

Appl. No.:

09/533707

Inventors:

Jacqueline S. Curran - Cranford NJ
Valerie A. Bell - Edison NJ
Steven M. Kuznicki - Whitehouse Station NJ
Tadeusz W. Langner - Linden NJ

Assignee:

Engelhard Corporation - Iselin NJ

International Classification:

C01B 3902

US Classification:

423700, 423712, 423DIG 21, 423DIG 24

Abstract:

Aluminosilicate zeolites are formed in a novel reaction medium which contains a silicate source and an aluminum source in an aqueous alkaline solution and which reaction medium further includes an additional electrolyte salt. The addition of the electrolyte salt provides nucleation sites for the zeolite so as to form very small crystals. In high silica reaction environments, it is possible to form high aluminum zeolites which contain occluded silicate and wherein the morphology of the zeolites comprise macroscopic aggregates of microcrystalline zeolites. The addition of the electrolyte salt can also decrease the reaction time or temperature needed for crystallization.

Appl. No.:

10/196943

Inventors:

Steven Kuznicki - Shitehouse Station NJ, US
Tadeusz Langner - Linden NJ, US
Jacqueline Curran - Cranford NJ, US
Valerie Bell - Edison NJ, US

International Classification:

C11D017/00

US Classification:

510/444000, 510/507000

Abstract:

This invention relates to zeolitic molecular sieve compositions and hybrid zeolite-silica compositions characterized by novel morphology in which the zeolite is present as macroscopic aggregates of microcrystalline zeolite. The zeolitic compositions of this invention have outstanding capability to complex multivalent cations, especially calcium due to the high exchange kinetics of the microcrystalline zeolite component and yet have the ease of handling due to the macroscopic aggregate assemblage.

Appl. No.:

11/377840

Inventors:

Valerie Bell - Edison NJ, US

William Dolan - Yardley PA, US

International Classification:

C01B 33/36

US Classification:

423716000

Abstract:

The effective pore diameter of ETS-4 can be controlled without thermal treatment by selecting various combinations of cations to exchange into ETS-4. The effect that any cation mixture has on the ETS-4 can be reduced to the weighted average of the effects of each cation present.
