MAINTAINING MOLECULAR SIEVE CATALYTIC ACTIVITY UNDER WATER VAPOR CONDITIONS |
摘要 |
The invention is directed to methods for protecting metalloaluminophosphate molecular sieves, particularly silicoalummophosphate (SAPO) molecular sieves, from loss of catalytic activity due to contact with a gas containing water The methods of the invention provide procedures that enable activated sieve to contact water vapor, within a certain range of time, temperature, and water partial pressure conditions, before the sieve becomes substantially deactivated. |
