Title:
HIGH-SILICA Y MOLECULAR SIEVE HAVING FAU TOPOLOGY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/211281
Kind Code:
A1
Abstract:
Disclosed in the present application is a high-silica Y molecular sieve having FAU topology. The anhydrous chemical constitution of the molecular sieve is as shown in formula I: kM•mR1•nR2•(Si xAl y)O 2 Formula I; M is selected from at least one of alkali metal elements; R1 and R2 represent organic templating agents; k represents the number of moles of the alkali metal element M corresponding to per mole of (Si xAl y)O 2, wherein k=0-0.20; m and n represent the numbers of moles of templating agents R1 and R2 corresponding to per mole of (Si xAl y)O 2, wherein m=0-0.20 and n=0.01-0.20; x and y respectively represent the mole fractions of Si and Al, 2x/y is equal to 7 to 40, and x+y=1; R1 and R2 are independently selected from one of nitrogen-containing heterocyclic compounds and derivatives thereof, and quaternary ammonium compounds. Also disclosed in the present application is a synthesis method for the high-silica Y molecular sieve having FAU topology.
