More Information
Summary:THE INVENTION IS DIRECTED TO A METHOD OF STABILIZING METALLOALUMINOPHOSPHATE MOLECULAR SIEVE AND CATALYST DERIVED THEREFROM. IN PARTICULAR, THE INVENTION IS DIRECTED TO A METHOD OF TREATING SUCH MOLECULAR SIEVES WITH CHEMISORBED AMMONIA, WHICH MAY BE EASILY DESORBED BEFORE OR DURING USE AND AFTER STORAGE. THE INENTION IS ALSO DIRECTED TO FORMULATING THE MOLECULAR SIEVE INTO A CATALYST USEFUL IN A PROCESS FOR PRODUCING OLEFIN(S), PREFERABLY EHTYLENE AND/OR PROPYLENE, FROM A FEEDSTOCK , PREFERABLY AN OXYGENATE CONTAINING FEEDSTOCK.
