Fluid catalyst conversion of alcohols and oxygenates to hydrocarbons

摘要

Alcohols and related oxygenates converted in a riser reactor and dense fluid catalyst bed (ZSM-5 cat), along with the catalyst, are 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 800 DEG F.
