Abstract
Improved processing of spent catalyst from an oxygenate-containing feedstock to olefins conversion process is realized through the employment of a barrier filter to treat a catalyst particle-containing flue gas resulting from a catalyst regenerator. The barrier filter serves to separate the catalyst particles from the flue gas. Catalyst material so recovered can, with or without classifying, subsequently be appropriately recycled and further used.
