Abstract:
A SAPO-11 silicoaluminophosphate molecular sieve, the molar composition of which after removing the template by calcination can be expressed in anhydrous oxides as Al2O3: yP2O5: zSiO2, in which y has a value of 0.60-1.20, and z has a value of 0.05-1.3; characterized in that after removing the template by calcination, said molecular sieve has the main X-ray diffraction data as listed in Table 3.TABLE 32&thgr;d100 Ã— I/I08.00-8.1011.04-10.91s9.45-9.609.35-9.21s13.05-13.156.78-6.73m15.70-15.905.64-5.57m20.20-20.404.39-4.35m21.15-21.654.20-4.10vs22.23-22.39 (doublet)3.99-3.97m22.73-22.90 (doublet)3.91-3.88m23.28-23.313.82-3.81m*m: 20-70â€ƒs: 70-90â€ƒvs: 90-100.
