Regenerering av SAPO- og/eller ALPO-molekylsikt med vannfattig viske eller damp

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 u...

More Information
Summary: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.
