Title:
CU-SAPO MOLECULAR SIEVE, SYNTHESIS METHOD THEREFOR AND CATALYTIC USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/152829
Kind Code:
A1
Abstract:
Disclosed are a Cu-SAPO molecular sieve with coexisting crystal phases of CHA and GME, a synthesis process therefor and the use thereof in a denitration reaction. An XRD diffraction pattern of the Cu-SAPO molecular sieve shows the characteristic of broad peaks and narrow peaks coexisting. An inorganic framework has the following chemical composition: wCu-(SixAlyPz)O2, wherein x, y and z respectively represent the molar fractions of Si, Al and P; the molar fraction ranges thereof are respectively x ＝ 0.01-0.28, y ＝ 0.35-0.55 and z ＝ 0.28-0.50, with x+y+z＝1; w is the molar number of Cu per mole of (SixAlyPz)O2; and w ＝ 0.001-0.124. The synthesized molecular sieve can be used as a catalyst for a selective reduction removal reaction of NOx.
