High silica Y molecular sieve having FAU topological structure and manufacturing method thereof

摘要

The present invention discloses a high silica Y molecular sieve having a FAU topological structure, wherein the anhydrous chemical composition of the molecular sieve is represented by the formula I, kM·mR1·nR2·(Si x Al y )O 2 ; wherein M is selected from at least one of alkali metal elements; R 1 , R 2 represents an organic templating agent; k represents the number of moles of the alkali metal element M corresponding to (Si x Al y )O 2 per 1 mol, and k=0 to 0.20; m and n represent the number of moles of the template agent R 1 and R 2 corresponding to (Si x Al y )O 2 per 1 mol, m=0-0.20, n=0.01-0.20; x and y represent mole fractions of Si and Al, respectively, and 2x/y=7-40, and x+y=1; R 1 , R 2 are independently selected from nitrogen-containing heterocyclic compounds, derivatives thereof, and quaternary ammonium compounds. The present invention further discloses a method for synthesizing a high silica Y molecular sieve having the FAU topological structure.
