Title:
A METHOD FOR MODIFYING MICROPORE MOLECULAR SIEVE OF SILICOALUMINUM PHOSPHATE BY USING METAL
Document Type and Number:
WIPO Patent Application WO/2008/019585
Kind Code:
A1
Abstract:
A method for modifying micropore molecular sieves of silicoaluminum phosphate
by using metals is provided. The said method comprises mixing the powder of molecular
sieves of silicoaluminum phosphate, such as SAPO-34, with a compound of alkaline
earth (Ca, Sr or Ba) and/or transition metal (Cu or Zn), by using immersion method
or mechanical grinding method. The modified molecular sieve can be used as catalyst
for converting oxygenate feeds into olefins, which has a higher initial selectivity
for low carbon olefins than unmodified molecular sieves.
