Rejuvenating SAPO molecular sieve by freeze drying |
| abstract |
Disclosed is a method of rejuvenating molecular sieve and molecular sieve catalyst. The method includes freeze drying a molecular sieve having a methanol conversion ratio of less than 1, or a catalyst containing molecular sieve and a binder having a methanol conversion ratio of less than 1. The rejuvenated molecular sieve or catalyst is used to make an olefin product from an oxygenate. The olefin product containing ethylene and propylene can then be used to make polyethylene and polypropylene, respectively. |
