The present invention provides a process for making an olefin product from
an oxygenate feedstock which comprises:a) contacting the feedstock in a
reaction zone with a catalyst comprising i) a molecular sieve having
defined pore openings and ii) a CO oxidation metal, under conditions
effective to convert the feedstock into an olefin product stream
comprising C.sub.2 C.sub.3 olefins and to form carbonaceous deposits on
the catalyst so as to provide a carbon-containing catalyst;b) contacting
at least a portion of the carbon-containing catalyst with a regeneration
medium comprising oxygen in a regeneration zone comprising a fluid bed
regenerator having a dense fluid phase and a dilute fluid phase under
conditions effective to obtain a regenerated catalyst portion, wherein
the difference between the temperature of the dilute phase and the
temperature of the dense phase is no greater than 100.degree. C.;c)
introducing said regenerated catalyst portion into said reaction zone;
andd) repeating steps a) c).
