AUFFRISCHUNG VON SAPO UND ODER ALPO- MOLEKULARSIEBEN MIT WASSERFREIER FLÜSSIGKEIT ODER DAMPF |
摘要 |
<p>This invention is to a method of rejuvenating a molecular sieve. The method includes contacting a molecular sieve having a methanol uptake index of less than 1, or a catalyst containing molecular sieve having a methanol uptake index of less than 1, with anhydrous liquid or vapor until the methanol uptake index is increased by at least 10%. The rejuvenated molecular sieve or catalyst can be used to make an olefin product from an oxygenate-containing feedstock. The preferred molecular sieve is a silicoaluminophosphate (SAPO) molecular sieve.</p> |
