US Patent:

6716338, Apr 6, 2004
Filed:

Jul 8, 2002
Appl. No.:

10/190992
Inventors:

Rostam Madon - Flemington NJ
David H. Harris - Mountainside NJ
Mingting Xu - Edison NJ
David Stockwell - Middlesex NJ
Bruce Lerner - Princeton Junction NJ
Glenn W. Dodwell - Bartlesville OK
Assignee:

Engelhard Corporation - Iselin NJ
International Classification:

B01J 2908
US Classification:

20812001, 208118, 502 64, 502 65, 502 68, 502 73, 502 79
Abstract:

A fluid catalytic cracking catalyst made from microspheres that initially contain kaolin, a dispersible boehmite alumina and a sodium silicate or silica sol binder. The kaolin portion contains hydrous kaolin and optionally spinel, or mullite, or both spinel and mullite made via kaolin which has been calcined through its characteristic exotherm. Calcination of the hydrous clay to metakaolin and formation of in-situ zeolite by treatment with sodium silicate yields a catalyst containing Y-faujasite and transforms the dispersible boehmite into a transitional alumina. The catalyst can be used to crack resid or resid-containing feeds as the alumina phase formed from the dispersible boehmite passivates nickel and vanadium contaminants.

Filed:

Jun 2, 2003
Appl. No.:

10/452257
Inventors:

Mingting Xu - Edison NJ, US
John Macaoay - Linden NJ, US
Assignee:

Engelhard Corporation - Iselin NJ
International Classification:

C01B039/38
US Classification:

423709, 423712, 423716, 423DIG 22, 20812001
Abstract:

A novel method of forming ZSM-5 comprises reacting calcined kaolin microspheres with silicate and a seed solution used for forming zeolite Y under conditions of pH, temperature, and time to yield ZSM-5 crystals formed in-situ on said calcined kaolin microspheres. The reaction medium does not contain any organic templates or ZSM-5 seeding crystals.

Filed:

May 19, 2003
Appl. No.:

10/440608
Inventors:

Mingting Xu - Edison NJ, US
David Matheson Stockwell - Westfield NJ, US
Assignee:

Engelhard Corporation - Iselin NJ
International Classification:

B01J029/08
US Classification:

20812001, 208118, 502 64, 502 65, 502 68, 502 73, 502 79
Abstract:

A fluid catalytic cracking catalyst is provided with a high porosity by in-situ crystallizing an aluminosilicate zeolite from a reactive microsphere comprising metakaolin and hydrous kaolin. Any calcination of the reactive microsphere before reaction with a zeolite-forming solution is done at low temperatures so as to ensure the hydrous kaolin is not converted to metakaolin.

The kaolin portion contains hydrous kaolin and optionally kaolin which has been calcined through its characteristic exotherm. Calcination of the hydrous clay to metakaolin and formation of in-situ zeolite by treatment with sodium silicate yields a catalyst containing Y-faujasite and transforms the dispersible boehmite into a transitional alumina which contains a gamma alumina phase. The transitional alumina may contain a delta alumina phase as well. The catalyst can be used to crack resid or resid-containing feeds as the alumina phase formed from the dispersible boehmite passivates nickel and vanadium contaminants.

208/120010, 208/118000, 502/064000, 502/068000, 502/079000
Abstract:

A fluid catalytic cracking catalyst made from microspheres that initially contain kaolin, a dispersible boehmite alumina and a sodium silicate or silica sol binder. The kaolin portion contains hydrous kaolin and a particular kaolin which has been calcined through its characteristic exotherm and which produces a catalyst having a novel morphology comprising a macroporous matrix and crystallized zeolite freely coating the walls of the pores of the matrix. Calcination of the hydrous kaolin to metakaolin and formation of in-situ zeolite by treatment with sodium silicate yields a catalyst containing Y-faujasite and transforms the dispersible boehmite into a transitional alumina. The catalyst can be used to crack resid or resid-containing feeds as the alumina phase formed from the dispersible boehmite passivates nickel and vanadium contaminants.
