Process for converting oxygenates to olefins using molecular sieve catalysts comprising desirable carbonaceous deposits |
摘要 |
The present invention relates to methods for selectively converting oxygenates to light olefins, preferably ethylene and propylene, in which desirable carbonaceous deposits are maintained on a total reaction volume of catalyst by totally regenerating only a portion of the total reaction volume of catalyst and mixing the regenerated portion with the unregenerated total reaction volume of catalyst.
