ABSTRACT:
Alcohols and related oxygenates are converted in a riser reactor and dense fluid catalyst bed (ZSM-5 zeolite catalyst) circulated through a plurality of satellite stripping-cooling zones for temperature control. Catalyst utilized comprises from 5 to 20 weight percent coke for activity and selectivity characteristics promoting the formation of olefins and aromatics at temperatures below about 427.degree. C. (800.degree. F.).
