International Classification:
C10G 1104
C10G 4704
US Classification:
208111
Abstract:
An novel class of iron-aluminum-phosphorus-silicon-oxide molecular sieves is disclosed which contain as framework constituents FeO. sub. 2. sup. -, and/or FeO. sub. 2. sup. -2, AlO. sub. 2. sup. -, PO. sub. 2. sup. + and SiO. sub. 2 tetrahedral oxide units.

Process For Modifying The Pore System Of Zeolite Lz-202

View page
US Patent:
5192727, Mar 9, 1993
Filed:
Aug 19, 1991
Appl. No.:
7/747050
Inventors:
Vinayan Nair - East White Plains NY
Donald F. Best - Mahopac NY
Lawrence D. Vail - Tappan NY
Assignee:
UOP - Des Plaines IL
International Classification:
B01J 2906
US Classification:
502 64
Abstract:
Zeolite LZ-202 and other zeolites synthesized in the absence of organic templating agents and having a crystal structure isotypic with the mineral mazzite are subjected to a three-step treatment to greatly increase their surface area, catalytic activity and adsorptive capacity for adsorbates having molecular dimensions as large as the SF. sub. 6 molecule. The treatment steps involve an initial conventional NH. sub. 4. sup. + ion-exchange, steaming at temperatures in excess of 300. degree. C. and a low-pH NH. sub. 4. sup. + ion-exchange at pH values below 4.
