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.
