Method For Heteroatom Lattice Substitution In Large And Extra-Large Pore Borosilicate Zeolites

View page
US Patent:
6468501, Oct 22, 2002
Filed:
Sep 14, 2000
Appl. No.:
09/662119
Inventors:
Stacey I. Zones - San Francisco CA
Assignee:
ChevronTexaco Corporation - San Ramon CA
International Classification:
C01B 3906
US Classification:
423713, 423714, 423715, 502 85, 502 61, 502 73, 502 74
Abstract:
The present invention provides a method for preparing a zeolite having lattice substituted heteroatoms. The method includes: (a) contacting a calcined borosilicate zeolite with an acid, thereby producing an at least partially deboronated zeolite; and (b) contacting the at least partially deboronated zeolite with a salt-containing aqueous solution comprising one or more salts selected from the group consisting of aluminum salt, gallium salt, and iron salt, thereby producing a silicate or borosilicate zeolite having a lattice comprising aluminum atoms; gallium atoms, iron atoms or a combination thereof. Step (b) is conducted at a pH of about 3. 5 or less. Preferably, step (a), step (b) or both are conducted at a temperature of from about ambient temperature to about 300Â C. , preferably, under stirring/tumbling.
